You'll crush for sure. Been down there climbing 3 times or so and still haven't been on WallOTW. Life is to short, go crush. I've gotta assume the high road
via Hamm's station is open but a quick call to confirm might be worth the pennies.
Camping will be easy, always has been and if you don't like the forest service cg (stayed there and never had another camper) you can more or ;ess camp anywhere. One trip a bud and I started with a case of Sierra and slowly deposited our empties next to our full cooler over 3 days until we left.
Its a special place and enjoy
