If you really want to see the "Charm" of Southern Illinois, you should visit MoonShine.
It is a real blast from the past. Check out their website before you start out. And do not trust the GPS or any directions. Get close and "ask a local" where it is. Motorcycle clubs use it for a meeting point, Jeep clubs, etc... The last time I went, the wife and I got there "early" and there were about 300 people behind us when we got our meal. I LOVE the place, but only go there a couple times a year. The "Adventure" is getting there. The meal is normal fare, but the atmosphere takes me back to the 50's......
