You will most likley not have cell reception at the camp ground, at all. Once we cross to the other side of the Mt for OFR, you may be able to get weak reception.
Please warn your wife, girl/boy friend, kids, mom, dad, dog, pool boy, etc that they may not be able to get ahold of you. There is a pay phone (if i remember correctly) in the resturaunt, but don't know the number.
