Oh, I had a trashy old 15 speed bike...it was really cheap. And I used to mountain bike at this place where I used to camp at. We used to ride all the way around the lake...which had to be about 10 or 12 miles. The trail around that lake was intense! It was right at the cliffs and if you weren't careful, you'd slip straight down into the lake...about a 15 foot drop.
