off road driving
This is where "The Hammers" event is held each year. A huge collection of off road racer/crawler hybrids, vendors, camping and a huge number of fans with their own 4-wheel Drive vehicles.
Much variety to choose from out here. Something for everyone, well almost. Don't take your PT Cruiser out in the sand like one fool did. I had to extract him 3 times with my Jeep.
There is The SledgeHammer, The Claw Hammer, The War Hammer & a few others around this canyon. Definitely worth a long weekend with whatever you're riding. You will want more after this trip!
