I am bringing Gaintfish up next weekend. I tried to get the company chalet but the owner may be using it. Gaintfish is fresh off a broken leg (he is doing well, back to running on pavement but no trail running yet) so backcountry camping might be pushing it. I tried to reserve a cmpsite in Elkmont but the online reservation system is not working. What are my chances of getting a campsite coming in thur evening?
