Longtime reader, first time poster. Also, tried for July 4th weekend this morning right at 7am. No luck. Called the Reservation Center just now to vent and they explained that camping for the entire Valley Floor was sold out by 7:10am. They said it is a function of simple supply and demand. There are several thousand people from all of over the world trying but only a few hundred campsites.by HikerFan - General Discussion
