14 days would be allot of time to spend in the Whitney Zone for sure! just go up and camp on the peak for a 2 weeks, only going down to resupply your water grin

It would be nice if normal back country permits operated a bit more like the PCT ones, or at least give you more than 24 hours out of wilderness.

It's a bit comical when you go for more then 2 weeks because your camping locations will not fit on the paper beyond that so your permit is sort of like a blank check, it only says when you plan to exit and where.
