Anyone have any info on the Briggs Cabin? I heard that it's a really nice place located in one of the canyons in the Panamints. I also heard something about a bridge that you have to go on to get to it. Is this place as good as they say it is? Also I heard that there's actually two cabins right next to each other, but one is nicer than the other. Do I need 4x4 to get there or can I get there in a regular truck?
