Teeds and Cal-c...
My two rides out there were with the help of wonderful friends from the area that let me use their TX legal XR 400 and KTM 520's. You don't have to have a "proper" Dual Sport type machine to get legal in many states and areas. With a few mods you can get a license. There are also other options about getting a tag for your bike. In the BBNP area I have never seen any real big deal about it anyway as long as you are respectiful of the place. Besides, once you are out there you are OUT there. This is not a crowded place for a reason. It is WAY the hell off the beaten path. Don't ride any hiking trails and just stay on the "roads" and you will have a blast. Besides, if you are not used to desert riding you will probably croak anyway and it will not matter. This is a beautiful area, but is is harsh and you have to be prepared. If you don't have water, tools, and the ability to change tires in 100 degree temps you might have a bad time. But get preped and go for it, you will not regret it. Teeds, how did you crash at Dirt Week?
