Donnie-
your makin this way too complicated dude
Be prepared for all weather from 28 degrees to 80 degrees, wind rain and frost and hurricane.... seriously....
Iffn it rains ( and it will) just wear hikin boots, mud don't get much worse than that... (ankle deep ) just kidding, even with a bit of rain, it is the tall grass that gets wet and soaks your shoes. Only time it will be a big problem is if it rains for daaays...
Demascus and the waters there in are about 20 minutes from camp. PHG has a hole or two he fishes on up in VA a little further away. I am sure he will chime in here.
If you have never done it, and money allows, I would strongly suggest you pay for the 3 day tag and fish the Holston and the stream near camp. Well worth the $$ just for the experience.
