Sorry I'm just now seeing this. I've been in CB for 7 weeks, with 1 more to go. I've biked the mountain just twice, but have done a ton of the trails in the area. And my 2 oldest boys (9 and 7) have been doing bike camp on the mountain twice a week. They are now officially better than me.
Curious as to your comment "they don't have a ton of runs". What are the other mountain bike destinations in the US in terms of downhill runs? I've always thought the CB mountain had a good number of runs with a wide variety of difficulty, but I've never been anywhere else to purely mountain bike. So I don't have much to compare to. I'm extremely fortunate that my in-laws own a condo up here, so there's never really a debate as to where we go in CO each summer, but I'd still like to know for future reference, guys trip, etc.
BTW, where did you camp and fly fish? Been doing quite a bit of that over the past 2 months as well. Well, the fly fishing at least. Too bad work gets in the way, but I've managed a few 3-4 day weekends.
