We ride pretty often, west side, mtb.
Bill, my uncle just moved to Denver from NYC and is getting his mtn legs right now...he's complained the last couple times that when we say "flat" we're flat lying
...but all we've done so far is the Breck nordic center and Marshall Mesa. If you'd like to come with us, he's learning and I'm recovering from a bloody knee, elbow and bruised hand I got being stupid at Marshall last Thursday.
We'll be out again as soon as it's dry, most evenings after work.
