I just returned from Green Ridge State Park in Maryland. It was my first time on "real" trails. I have read that the trails there are pretty tame, but if that's tame, I don't think I'll venture anywhere else! Granted it was my first time,and my Unlimited Sport is stock, but I thought the trails were pretty technical. That said, my Jeep was awesome. I was clearly more nervous than it was. It ascended and descended with ease and I kept thinking that my daily driver was going to break. How much abuse can these JK's take? I think I'd be afraid to take it offroad more than a few times a year. What is a common part to break, if anything? I look forward to hearing your thoughts.
