I live in Wichita and theres not much close here.
Mine Creek battle fied and Fort Scott are about 150 Miles east.
Down in the south east corner of the state is Baxter Springs and of coures Prarie Groove and Pea Ridege ara about 4-5 hours in Arkansas.

Here's a good kansas civil war site.

Wichita has a couple of reenactor groups and I think they may still have a round table but not sure.
I'm amazed at the amount of relics we find out here.
Email me when you get out here. I'll try to help ya out.
