I wouldn't recommend riding Hobby Park if it's your first time on a mountain bike. The single track is tough and technical. There is also at least one impossible hill that's like riding your bike up a wall. For some insane reason I let my buds talk me into riding here when we were done at Salem Lake. My thighs were screaming for mercy and not to mention my arms took quite a beating since I don't have front suspension on my bike (yet). That doesn't mean I didn't have a good time. I think this is a great trail to test your biking skills. If I were to do it again, I would probably ride Hobby Park first and then shoot the gully at Salem Lake.
