You might get a Woodalls Camp Directory 2003 before you leave. It lists CG in all the states both private and some public (state/nat'l parks). Then you will have an idea of some alternate places just in case. You could also check an Atlas/Gazatteer(some libraries carry them) for that area to see what other CGs there might be. Also, the internet can give you some info for CG's in the area. Knowing that Nat'l Parks are very busy places (and more so with people traveling by car now) it is alway good to have an alternative plan. Just some thoughts. Leigh
