Just to throw out some info on this place...
Don't go out to Area52 expecting to "ride" your bike like you normally ride your bike. I went out there a few years back and we had a good time, but there are no "trails" to speak of. It's a playground I guess, if you can find the playground areas. Expect lots of scree(sp?), HAB and expect an adventure. If you are the type who is looking for an adventure for a day then you will have a good time. If not then you will likely not have a good time.
Just to make it clear, I am no freerider whatsoever. So I probably didn't find the good stuff b/c I can't ride that kind of stuff. I did find some 2 to 3 footers to flat to play around on but all in all, it was fun but I've never felt I needed to go back. Just some food for thought for those who have never been.
