I haven't been riding that long, but have been a commuter about 12 years, with some road and club rides. Had not seriously considered mountain biking, as it seemed like riding with no payoff, i.e. no destination. This year, I obtained a Trek Marlin 5 through my employer's fitness program, and was ambivalent about trying cross-country riding, or converting it to a heavy-weather commuter. Went to a beginner's group ride, and seem to be hooked! No destination? Well, fun and fellowship are rewards in themselves, and an hour on the trails is much more strenuous than two hours on the road for me. And, practicing mountain biking skills should help my winter riding.

Congratulations on the Fuse, that looks like a great ride.
