Spoke to Jon Davis, he said best thing to do for my situation would be to stay in South Lake Tahoe on Tuesday then drive to Loon Lake Wednesday morning. About a 60 plus mile drive that takes about 1-2 hours. Think we may do that since I need to leave my tow rig there anyway and Sharon really wants to check out the lake area.
I will let you know what I find. Jon also said to give Dave Brown a call since he has a ton of experience on and around the Rubicon.
