Hey Jim,
I have been trying to get into the classes down in Boulder, I just need to scavenge the money so that I can go. And by Gauntlet you mean gauntlet training right? But i would love to come and train with you guys. Currently i have been going to the Colorado National Parkour Jam to further myself into the Parkour crowd and I plan on going to the Jams tommorow in Denver and also the jam on Monday in Boulder. Maybe I will see you there and introduce myself in person.
As for any hotspots... there are little to none... except for the surrounding scools such as Peak to Peak, Centaurus, Ryan Elementary, etc. Thouse have been the places that i have been training. There is also a private school named Alexander Dawson School which has some really good play grounds and good places to practice and train.
