Welcome to the forum Locojoe. I've not thought of Kansas as being in the midwest. I thought they were in the Great Plains. It's cool though.
I won't be attending the Kansas swap meet, but I'd like to attend the one in Ann Arbor on April 25.

I think that any swap meet that uses a photo like this to advertise on their web site is probably going to be fun to attend.
