I should add that the jeep road out of Poker flat towards Laporte is really not that bad on a regular dirt bike. Actually it a blast cause it forces you to be on your game for a good stretch.
The other thing that makes riding up that way is there is an old cemetery up at the top which is cool to walk thru and and old mining town. I can't think of the name of it off the top of my head. I bet Juan knows.
