So far as I know, there are four of us that live in Arkansas. Beside you and me, there is MadcatNU (don't know where, and he last posted in May of this year) and Ibleedred (who lives on the west side of Little Rock, but hasn't posted since '05).
Oh, and Huskerhawg was from Springdale, originally, but has moved to Nebraska.
That's all I can think of, at the moment. So, in total, there are three of us on the board that are located in or near central Arkansas. I've not found any kind of a Husker chapter in or near central Arkansas.
As I recall, Fort Smith used to have a thriving Husker chapter - I can recall seeing their banner at Husker games in the early '70s, but try as I might I can't find any evidence that the chapter is still in existence.
