Every once in a while the road/trail will follow a wash. These are areas that become roaring rivers during our flash floods. When the water goes away what is left is some very loose and deep sand that doesn't pack. It really makes you work when riding a motorcycle in it. The T-dub is pretty good with it's big tires, but you still need to drop the air pressure to 11 or 12 psi if you want to make it as easy as possible.
