Damn haha, I barely even put 15,000 miles on my car in the two years I've owned it. But I hardly go anywhere far.

I really wanna get into downhill mountain biking, I've been debating a Diamondback 29er for a while, and there's tons of really nice trails around here.
It sounds like one of the best ways to spend the summer, cruise through the mountains and then ride for a while!
Any tips for someone looking to get into it?
