Arkansas does have some great riding. I went up there on a Labor Day weekend in 2013. It was a bunch of fun! The only thing you have to be careful of is that there are lotsa dry counties up there and you need to plan ahead if you're looking for buttery nipples.
Yep. Dollywood at Pigeon Forge and Gatlinburg are just over the mountain on 441 which is a pretty good ride in itself. Shopping outlets galore for the ladies.
Wheels Through Time is something to see and experience. Dale is a great guy and if you hit it on a not too busy day he'll give you the grand tour and maybe even fire up one of the scooters ( sidecar ) and take you for a ride up the hill in back. ( it was fun )
