Add me to the first-timer's club. I think I could have a lot of fun on a mtn bike!

We camped over the weekend; the campground has 8.5 miles of mtn bike trail. I had the old beater Gary Fisher MTB I bought to keep my pretty new Trek Pilot off the rough terrain I usually end up on when we're camping. DH & I took the 6-year-old grandson on the mtn bike trails. He loved it, DH loved it & I really loved it! I know I was terribly slow and I bypassed the ramps, but I loved the concentration it took to maneuver the trail. We're ready to go again. Only problem is that the closest trails are about an hour away, so it would have to be a weekend-only activity for us. I'm ready to look for a better used mtn bike and I think DH could easily be convinced to become a two-bike owner.
