the 4 digit roads are probably county roads, FS roads are signs 3 digit, 553, 567, and a few others I cannot recall of hand.
I'm sure there is someone who can 'splain it better. been a long day.
To me, you are an "upper midwesterner"
You ever get over to Silver Lake Dunes much ?
I haven't been there since I was a kid, have always wanted to go back in my own under powered junk, just to play. ( My first REAL introduction to 4wheelin ! )
I was in the dune in a 72 K5 Blazer, belonged to a neighbor of the cabin we were renting, then we took one of the dune rides, they were driving modified International trucks with rows of seats and running DC3 aircraft tires.
Someday I'll get there with my kid, she'll love it.
Anyway, welcome and Uwharrie will be a nice diversion from the daily grind. DOn't forget, Tellico is just another 4.5 hours further west ! (6.5 hour trip from Cary )
