Today's headline from the Des Moines Register says that the Cedar Bridge, the one evidently most famous from the movie, has burned down. There are 6 remaining covered bridges in the country. Anyways, you can read more on it here.
It's not sad because of the book or movie, which I never read, so much as it's a place I've visited, one of the lovely historic places from my childhood in a lovely countryside. Goodbye bridge! I'm glad you existed!
