That trail looks nice Dave!
Sadly, I'm already out for the summer. Going downhill way too fast and missed my corner at Red Rocks (Colo. Spgs) week before last
Ruined my golf season too.
I hope you heal up and can get back to it quickly! Stay active is my best suggestion, people tend to give up and lose a ton of fitness when recovering, I've made that mistake...
I injured my left shoulder about 1.5 years ago, it's no fun. I lost my long head bicep tendon, rotator cuff muscles have been weak but are now starting to get stronger. That bicep tendon was causing issues that are now clearing up after it ruptured. The surgeon calls it "Elway Arm" after John Elway's rupture in '97. He went on to win the superbowl that year and the next year so I should be ok. It looks weird though, more of the bicep muscle is near the forearm vs the right side.
Endo, a friend of mine still rides a Knolly Chilcotin (I think!

), looks like the same bike but it's 26". There's getting to be a lot of older riders, keep doing it... it keeps us looking young! Yoga and weights seem to be very important too. The 40+ age group is actually extremely fast at races here in CO, the winner of the 40+ category would have been top 20 in the pro category and beat the 21-39 y/o amateur winner easily.

Tone Depth, we're still busting through snow drifts here in CO!
