If you ever have a pile of money and some time and a passport, go to Gaming, Austria in the fall. The colors will stay in your mind forever. And then go back in the winter when the waterfall there will be frozen blue. In the spring, the meadows will be covered with wildflowers. You can probably tell that I am missing four real seasons.
James Thurber is my favorite humorist nowadays- if you have never enjoyed his writing- start with James Thurber's Carnival.
Ray Bradbury is another fall favorite- but he couldn't be more different than Thurber. The movie Something Wicked This Way Comes is very good, but don't let the PG rating fool you. It has children as its stars, but the story and movie are really not for kids.
I guess I am in a melancholic mood, because Bradbury's short story All Summer in a Day is speaking to me. I found the old 70's film on Youtube. The story is better, but check it out.
