First off, I don't know why they called it the Color RUN - most people WALKED - which was fine. I just want everyone who says "I'm not a runner" to realize they can do this! We ran for about 1/3 of it, and I think we ran a lot more than most people.
Take your kids - you don't have to pay to register the younger ones - they'll love it! Take lots of pictures! We LOVED it!
