I am going on a trip to Arizona. While there, I plan to see the Grand Canyon and the O.K. Corral. I've read about the former, and first learned about it in an episode of Star Trek. It sounds kind of interesting, but it's also kind of sad that Tombstone's finest feature is that some gang members who didn't like each other got in a fight and shot one another to death.
The Grand Canyon also sounds very interesting. It's a giant red rift in the ground, and has probably the same amount of romantic value as Niagara Falls.
