And I partook.
My gripe? There were WAY too many people out on the course at the same time. The obstacles couldn't handle the volume and you'd be running along the path and then come to bottle-necked traffic as thick as you'd find in L.A. Stand around and wait for 10-15 minutes then finally get to climb the cargo net and move on. Trying to run faster than the groups around you to get ahead of them for the next obstacle.
It was still fun, but I don't know if I want to do it again next year. Time will tell if I'll be ready to get DIRTY again.
