I know there are several Panteras in the Kansas City area but haven't been fortunate enough to meet up with any of them so can't really be of any help with names, addresses,etc.
We have 3 cars in and around Topeka and several of us make the cruises here in town which are held every Saturday evening during warm weather as well as attend quite a few car shows in the Eastern half of Kansas. We are probably the closest group to your home. I know Sedalia is a good distance from here but its got to be closer than Canada
If you have questions or I can be of any help to you, please drop me an e-mail.
