Our Animal Minds show questions whether dogs feel guilt...or whether we're just reading our own meanings into those puppy dog eyes. Dog owners, if you think you've got an incriminating photo of your canine looking remorseful, send it our way.

Watching music being made is as much a delight for the ears as one for the eyes. Here are our favorite collections of photographs featuring classical music performers, performances, and venues from across the web.

"Chemical plants on shore are considered prime source of pollution." (Marc St. Gil, Lake Charles, Louisiana, June 1972. National Archives, EPA Documerica Project)

These photos are beautiful. They're also sad, and hopeful, and quaint.

In the 1970s the EPA commissioned photographers to roam the country and document daily life in places like coal mines, riverbanks, cities, and even an early clean tech conference in a motel parking lot. The images were meant to be a baseline to measure change in the years to come, but there was no funding to go back to the original places.

The Documerica project photos are up on Flickr now (hat tip to FastCoExist for posting some of these gems). It's an overwhelming album of nostalgia for everyday life, but also, devastatingly depressing to see how dirty and toxic so many inhabited places could be in the 1970s ... and how little has changed in some places today.

What makes the project so powerful though, is how beautiful the photography is, even of the mundane moments, or tragic scenarios like kids playing in a river next to a power plant.

Strum through the albums yourself and share your favorites with us on our Facebook page and we'll add more pics to this post later on.

In the albums, there are also early editions of clean technology, like Frank Lodge's photos from the first First Symposium on Low Pollution Power Systems held at what seems to be a motel parking lot.

"Children play in yard of Ruston home, while Tacoma smelter stack showers area with arsenic and lead residue." (Gene Daniels. Ruston, Washington, August 1972. National Archives, EPA Documerica Project)

David Falconer documented the fuel shortage in the west during the 1970s, as well as water pollution in the area at the time.  (David Falconer, National Arcives, EPA Documerica Project)

On the three-month anniversary of Sandy, WNYC took a week-long road trip from Cape May, NJ to Montauk, NY to visit coastal communities and see how their recovery is coming along.

Our year-end photo project asked you to submit your best cell phone shots of the year. We got hundreds of submissions, and now New York Times senior staff photographer and Lens blog co-editor James Estrin picks his favorites. See Jim's favorites below, and be sure to check out all the submissions here.

A clever take on the works of DaVinci wins our first-ever Halloween Costume Contest. And we got so many great entries, we couldn't resist putting together a slideshow of our favorites -- feast your eyes on all the costume greatness.

We’ll be updating this throughout the day. Send your photos to transponation@gmail.com or @transportnation.  ‘Cause we’d like to share them.

Mt. Baker, Washington, July 2, 2012 (via WASDOT)

While the heat pounds the poor souls at sea level, this mountain road on Mt. Baker, Washington is still a canyon of snow.

The Washington State Department of Transportation posted this photo on their Facebook page. (Naturally we "like" each other from our Facebook page, which you should like too!)

WASDOT writes: "This photo was taken July 2nd as crews are still working to clear the road up to Artist Point."

The most conspicuous collection of forgotten bikes in one photo comes from the well-to-do Upper East Side at Lexington Ave and 67th st.

We've received more the 400 photos of bike blight around New York City in our mapping project. That's about 10 times the total number of abandoned bikes the city has removed in the past 18 months.

Tomorrow we submit them all to the city for inspection and potential removal. We'll ask you to you check back and see how many of these rusted frames (or saran wrapped beach cruisers) are eventually removed. For now, have a gander below at our favorite busted bikes chosen for photographic merit, level of "abandonedness," fun factor, and just because we liked them.

Pick your own favorites from the full gallery here. See the map, and read all about derelict bikes, the laws and stats here.

THE "MOST ABANDONED" BIKES:

Some parts remain, mild street trash tumbleweed factor. Park Slope, Brooklyn.

Bent frame, creeping rust, sun bleached belly. Pretty abandoned in Prospect Heights, Brooklyn.

BEST PILE OF KIDS BIKES:

We've found many piles of bikes -- which we fear tell sordid (or at least hoarding) stories. This was the most flagrant from Central Park North.

UNIQUE CASTOFFS:

Part art project, part bulletin board, this Williamsburg fixture hosts flyers, string, saran wrap and a teddy bear. Does that make it less abandoned or more?

That's a twofer. Photographer comment:  "I mean? This also has been here for over 6 years." From 9th Street and Ave C, Lower East Side.

More wheels does not always mean less abandoned. 10th street and 6th Ave, Brooklyn.

How long does it take to grow a few feet of vines? Tribeca.

 BEST PHOTOGRAPHY:

Deceptively unrideable in Midtown.

We call this one: arsty arcs. Downtown Brooklyn.

BEST COMMENT:

Though far less abandoned than other bikes, this one comes with a standout caption. "If NYC can also remove the dudes selling crack at this location, that would be great, too!" 167th Street, Manhattan

If the Department of Sanitation of NY finds a bike to be abandoned, it is tagged for seven days, then removed.

We asked you to submit your photos of Hurricane Irene, which moved from the Outer Banks of North Carolina to New England over the weekend, weakening from a Type 1 hurricane to a tropical storm, killing at least 16 people and shutting down public transit in Philadelphia, Boston and New York. Here are some of the submissions we've received. Do you have a photo from the storm? Submit it here, or call us at 1-877-8-MY-TAKE and tell us about your Hurricane Irene experience.

TN readers: here's your summer assignment: while you're vacationing this summer, take a picture of what you think is a good representation of a transportation mode, wherever you happen to be.

We're interested in seeing what strikes you about transportation and transit in other places. Are the street signs clear? How's the boat traffic?  Are the taxis wheelchair-friendly?

And have a happy TranspoVacation!

The White House has announced that it will not release photos of Osama bin Laden’s death. Quoting the transcript of President Obama’s upcoming interview with 60 Minutes, set to air this Sunday, White House Spokesperson Jay Carney told reporters that, “It is important for us to make sure that very graphic photos of somebody who was shot in the head are not floating around as an incitement to further violence or as a propaganda tool.” Some very graphic photos from the raid have already been published by The Guardian. Is the release of graphic photos a good idea? 

(New York, NY -- Stephen Nessen, WNYC) The 109-year old Willis Avenue bridge drifted down the East River early Tuesday morning as it headed for Jersey City. It was replaced last July as part of a $612 million project. Full slide show here.

The world has been shocked by three photographs released by German magazine Der Spiegel. The photos depict dead civilians in Afghanistan and U.S. Soldiers who are accused of killing them for sport. Part of a self-designated “Kill Team,” the soldiers appear to be making fun of their victims. In one, a soldier smiles as he holds up the head of a civilian corpse. In another, two dead civilians appear to be tied at the wrists. The U.S. Army has released a statement calling the soldiers’ actions “repugnant,” and assuring the public that prosecution is underway. But will this be enough to stem the tide of what appears to be another Abu Ghraib?

Our partner The Takeaway asked for your snapshots and sounds from your daily commute. They got some striking photos, some cluttered traffic and a healthy dose of personality.

See the full slideshow here.

All this week, we've talked about class on The Takeaway. And we gave you an assignment: take a photo of something in or around your house that indicates what class you're in. 

You sent us some great photos, which you can see after the jump — and we've asked photographer Karen Marshall to help curate them. Marshall is a documentary photographer. She's on the faculty at the International Center of Photography, where she is a seminar leader in the photojournalism documentary program.

We took a group of 14 Rookies from the Bronx and Queens down to Washington DC to see the sights. There were 17 of us, traveling on a double-decker bus, staying in a hostel.

This fall, we began a new broadcast workshop in Flushing, Queens in partnership with the Flushing YMCA. During the past month, the Rookies have started to roll through their lessons, putting their new skills to practice. They are well on their way to making their radio documentaries.

One of the Rookies asked me 'why is it that we have to throw the party on a brick cold day?' But, despite the arctic temperature and the wind chill factor Rookies from past and present showed up. We all came together and celebrated being a part of the Rookies family for the past 10 years and looking ahead to many more years.
