Riding areas - Arkansas and Missouri

[blitz11]

Greetings.

For the first time in 44 years, i have the summer off of work. My brother is retiring from Caterpillar in Manhattan, KS after 36 years, in May and he's done working for good. I am going to continue to teach at Montana State - i find it fun. Gives me someting to do in winter (SE - May).

I am going to travel from MT to KS to ride with him in Kansas, and we'd like to also ride in AR and MO.

Can anyone please recommend riding areas, state/nat'l forests where we could ride in those two states? I'd like to spend about a week - 10 days in those two states, riding as much as we can. I am unfamiliar with those states, but would like to spend time there.

Thanks very much in advance.
