I fly with t' Northern Colorado Rocketry Club primarily and with Tripoli Colorado. NCR flys in t' beautiful Pawnee Grasslands with a standin' waiver t' 20,000 feet AGL. Ya scallywag! It's a fabulous area with two launch sites, t' Atlas and t' North Site. Atlas is for winter use with a waver o' 12,000 feet AGL. Tripoli Colorado flys at Hartsel and offers extreme views and bison too. (Bison fencin' is nay easily crossed).
Both clubs have incredibly friendly and knowledgeable members. Highly recommended.
I'm a BAR havin' a blast figurin' things out. I've crashed, lost, arrr, and damaged a significant number o' rockets, but still love doin' it.
