I actually had no idea until maybe 5 or 6 years ago. And the way I realized it was a total fluke. I was looking up something on IMDB and somehow made the connection.

I have a place in my heart for Animal House. During the 2007 edition of Cycle Oregon we spent a night just outside Cottage Grove, and there were shuttles into town. Cottage Grove is where the homecoming parade scenes were filmed. If you closed your eyes and turned back the clock in your mind you could really see it. In fact, I took a photo of an old sign for a restaurant. When I watched the film again later I realized that you can see that very sign for a split second. It as still there after all those decades.
