As toolmanmike said above, we have our own "tasting", nothing linked to the hosting club. Bring some beer specific to Kansas if you'd like, and try (and maybe even take home) some beers from Minnesota and Wisconsin. I don't know what Illinois had to offer, a co-worker said IL doesn't have any good beer, maybe the members there know something about it.
The car show is the largest Mopar show west of the Mississippi, essentially the third largest show after Carlisle, and the Nationals. I attend every year and have met many great folks, it's always a fun time.
