We stayed in a Pigeon Forge campground years ago and you would have thought I was in New York city we were so tight...
beautiful country around there, but sorry, Pigeon Forge was a tourist trap as far as camping goes
maybe its changed, but do know it was still worth the trip to be able to do the smoky mountains, gatlinburg, etc...
As far as communications, we've found the cellphone thru the truck's bluetooth is the easiest on me...
I just ask the wife to call me when she is in position to watch the 'other' side, and say things like
STOP... which is the most important command, everything else can be negotiated
but, if she never says anything, then I'm not sure if we still have a phone connection, so I ask her to say something periodically like "keep coming" ...
