I had not heard of The Color Run until about a month ago, but I can now say that you're missing out if you've never been to one. It was an awesome event with thousands in attendance. I'm not sure how many were there - I think I heard one of the announcers say 9,000 - but it was a sea of people everywhere you looked. Everyone was in a good mood and everyone was happy to have their picture taken. If you want to look for pictures of yourself or someone you know, there are 168 pictures in the full gallery.
When you get to the bottom of this page, you'll see what it's like to be in the middle of a big red cloud of color powder and a picture of what my camera looked like when I came out of it.
