I'm a wimp I went on one of those Hueston Woods trails, and they were only two-three feet wide, and there was a part where it did a steep slant into a muddy riverbank, then sharply up the other side and I did a jockey crouch, terrified my horse would misstep. Combine that with the horse I was riding was in a tom thumb with 5" shanks that required both hands and almost all my strength to turn, and completely dead to my leg *shudder* I gave up halfway through.
I'm a wimp though. Sneeze/cough and I feel like I'm going to pitch forward. Trip and I almost do a flying dismount. Of course, I also can sit a good buck and not notice lol.
