While living not so far away from Seymour, we visited their hamburger days celebration maybe ten years ago for the first and last time. It was a useless trip. First off, there was not one place in Seymour that sold hamburgers on a regular basis throughout the year (there was a fast food place, forget which, out on the highway).
We went there expecting to see some sights, or shows, or something worthwhile, but especially we each wanted a hamburger and a souvenir tee shirt.
There was not much going on, they were cooking a giant hamburger, whoop-ti-do, but pretty much everything else was for the kids, face-painting, etc. We went to the front gate, and admission was eight dollars each. We could see the stands selling the burgers and tee shirts just inside, with whatever other events further on.
We told the cashier we just wanted the two items, and could we just go over and get them, then leave. Nope. You pay the admission, or you don't get in.
We don't like being ripped off, so we went downtown and found a tavern with a sign outside offering burgers, that day only. So we went in and had a beer with the locals, while we all commiserated that you couldn't find a burger in the famed home of the burger.
Then we took the money we would have spent in Seymour and donated it to a casino in Green Bay instead.
I wrote the Seymour Chamber of Commerce about how they were throwing sales away, should sell the burgers and shirts outside the grounds, never got a response. Oh well, too bad, good-bye to them.
We did like the little burger museum downtown though, lots of old stuff.
