I heard about the World Wide Photowalk last year but it was too late to register. This year I got to go and take pictures in Tempe. There were over 32,000 people who participated around the world taking photos. Here is more information about the project: http://worldwidephotowalk.com/
In our group there were over 50 people taking photos. I am have seen a few photos people took and they are stunning and amazing!
Here is a flikr group set up for our group: http://www.flickr.com/groups/1181291@N23/pool/
The leader of our group Trevor Dayley even arranged to have a few models come along for anyone that wanted to photograph them. Pretty cool.
Here are some of the photos I took today:
