I'll be there for sure.

Campsites sell out fast, do NOT come unregistered. My advice is to get there mid-week, no later, to have a chance at a decent site. Otherwise, they will cram you in wherever they can. If that is not possible (especially with such a long drive!) then yea, I'd get with a friend that will be there ahead of you, to hold you a spot, or share a tent.

Also, be aware there are two sides to the camping. One side is meant as family camping, with a strict curfew for noise and fires. Across the road, it is a bit more relaxed, but it can be very noisy, and you do have to deal with a lot of drunken revelers.

Oh, and be prepared for the mountain weather. It changes on a dime. Extra tarps for rain and wind protection are a good bet, extra ropes, bungee cords, etc. are always a good plan. Temps range anywhere from the low 40's up through the high 70's. Be prepared!
