Murk,
If you are riding in Oct. try the Helena Blues Fest in Helena, AR just across the MS River. Great 3 day festival. Lots of blues on the banks of the river. There will also be alot of riders there. Hotels are few, but they do have tent camping and casino is just across river in MS.
As far as 'Any State' Travel info, ya gotta ask the locals. They know.
Let me think about it and I will make some suggestions for your travels to MS. I just need to know what your interests are. I thought about going into guided Tours at one time.
