While looking out the window of the airplane, seeing all sorts of landscapes between San Francisco and Chicago, I've added a new goal to my list of things to do. I'd really like to drive across the US or maybe take a train. There's just so much variety of different lanscapes - mountains, steppes, plains, etc., it seems it really should be experienced first-hand rather than just jetting over it at 30,000 feet. Maybe it won't look so impressive or interesting up close, but I have to find out.
