I can tell you a few things about the area in general:
1) Contact Sheriff Cody Carpenter in Waldron, Ar for local information in Scott County. He's a good man AND a straight shooter.
2) There is a small museum (it doesn't look like a museum) on the North side of Waldron that is most definitely worth the time to visit.
3) There is a definite problem with Meth Labs in the Quachita Mountains. The problem is less in Scott County but grows as you go more South towards Mena, Ar.
4) Going from Waldron, Ar, westward towards Heavener, Ok and Poteau, Ok, is a very active area for seeing most unusual things in the early night skies (sunset to 9:12pm)
5) In Scott County, Knoppers Ford is a good place to camp.
6) Gasoline costs $0.10 per gal more in Scott County than in the rest of Arkansas.
7) There are some truly good people in this part of Arkansas,,and a few truly bad ones as well. It's very easy to tell who is who, as you meet the locals.
8) Scott County is DRY. Many of the counties in this part of Ar are dry. Fort Smith is wet, though.
