Sounds like you need an REI fix? If you need an excuse to buy the sleeping bag then make a reservation to stay at one of the Forest Service cabins. Less extreme than tent camping. Lots of fun.
I got back from my ride about 30 or 40 min ago. The trails were bumpy and tough to ride on so I ended up on roads. Stopped to talk to a friend out on his fatback bike. He had a much easier time on the trails.
