I think he means Saline Valley in CA.....next to Death Valley. :uh:
Funktree,
I lived in Saline Valley for a couple of years mining gold with my grandfather back in the early 80s. I don't have any idea about green stickers, et al, but most of the area was open when I was there. Do your in-laws live out there, also? Our claim was at the base of Marble Canyon. If they're in the area, they'll know right where it's at.
The terrain is AWESOME (literally)!!!! The views from the elevations cannot be believed. It makes you feel really insignificant. It ranges all the way from high mountain passes (usually very loose shale) to salt flats in the basins. You didn't say what your were taking out there, but needless to say it should be in perfect running condition and prepped to the max. This is one area you do not want to break down in. If you get a chance check in with the local Honda dealer (can't remember the name) and see if any locals are heading out that way.
Speaking of that, if you do go adventuring out there (especially alone), it would be wise to leave a flight plan with the ranger's office in Bishop. That way if you don't check in after a certain time they will sent out a recon party to check on you. It's better to be safe than dead! Make sure you also pack a survival blanket and first aid kit. I could tell you some really gruesome stories, but my fingers are getting tired.
Check out Dunes Nat. park if you get a chance. It's incredible, but you can't ride on it. Also, if someone can guide you to the hot springs at the end of Marble Canyon, there used to be some incredible babes that came out from LA to skinny dip.....don't bring the Mrs. :p
