I did it in 06 and it was cool. It was my first Disney race so I was all jazzed up. Overall I would call it a good race. We ran through the Lights, Motors, Action and got on the big screen. That was neat.
There was a negative though. I didn't have a car so to get my packet took about 2 hours and a few bus transfers. To get to the race, I had to get a taxi and with road closures we had to go around, it cost $20 to go from ASMo to the sports complex. I should have run to the start.
