Me! Though I haven't been able to work out what sort of MTB-ing it is, XC or DH (or something else I don't know about).
It's mostly through woods/forests/parks, and it's on an off-the-rack hardtail (Trek 6500 disc).
I love it, though. I either fall off or almost fall off with terrifying near-misses and skids on every ride, very exciting.. and I also love getting good n' muddy. I'd do it more if I had the time, and more riding buddies, as it is, I only manage a ride every fortnight or so at best, and usually on me tod
