I had a blast as well. I met a lot of new people (although sadly I don't think I met any ExPo'ers), and my wife and kids enjoyed the other families that attended. I guess the biggest disappointment for me is that the event is so large that it's nearly impossible to meet and seek out all the people you would like to.
I ran Fins, Gold Bar Rim, Poison Spider Mesa, Moab Rim and Klondike Bluffs in my 5 days there. Moab Rim was certainly the most memorable, given the challenging obstacles and white-knuckle, off-camber driving with drop-offs down to the river. My wife walked the entire first mile, wanting nothing to do with those steep ledges....
Anyway - I'll add a few pics/videos from my collection. I'd love to see others.
