Today we're doing a scavenger hunt with your phones. You are going to take a picture with your phone and immediately e-mail it to the address read74arc80leave@photos.flickr.com.

Be sure to include your number in any photo you might take. That way it can be quickly added to your total. Include the number of the photo as well.

Try to respect people's privacy and take photos that don't have people in them. Stay out of areas that you're not supposed to be in. Be as quiet as possible.
