July is Photo Month! Our new challenge is to submit your pictures on the theme of "STRESS." What makes you stressed out? What makes you relax? Do you thrive on stress?

Submit your shots to our Brian Lehrer Show Flickr Page now (more detailed instructions here) and we'll discuss the results on the air next week!
