I did a 5 mile mtb ride in Estabrook Woods main trail, with one extra loop thrown in. It's only the second time I've been on my mtb this year, so I didn't want to do anything crazy. I managed to not fall or have to walk up any hills (there was only one bigger one), but i still always feel like I'm being jostled to death on the mtb, even with full suspension. It's just such a different feeling than being on the road. It was great to be out in the woods, though.
