Besides these ah, let's call them "unique" events, the one thing that struck me was that this festival was the Swiss equivalent of NASCAR (Granted, I have not yet attended the International Trucker and Country Festival in Interlaken).
Obviously there was no race track here, but there were huge parking lots filled with a combination of tents, campers, and cars, half-naked men sleeping beside them, and guys drinking beer in the river. People wore their tickets NASCAR style-- as badges of pride--around their necks on lanyards, and they somehow found sitting in the 93-degree sun to watch a bunch of Swiss guys roll around in the sawdust worthwhile. And while I did not find any corn dogs or turkey legs, there was a nice offering of American food, including DoNuts.
I always love a good DoNut.
