I am happiest when I am on the road, travelling someplace but I could not be a truck driver because they are always on an impossible deadline and have to drive something wayyyyyyy too big.
If I could afford it I would drive and SUV, I like things about that size. I can't afford to drive them though, so I drive a very economical compact car and like it well enough. The first month I had it I drove to South Dakota in it.
My idea of hapiness would be extended road trips, like a comet, all over North America. I have never driven in Europe or any other continent, would like to try that one day. Travelling in Eurrope is different for me because it is usually with a group on a bus and you see what they want you to see. I don;t like being a tourist, I would rather be a traveller.
I also like trains. I have not had much experence on them but I would love to go cross country in a sleeper car, and a good book. Harrison Ford played John Book in Witness.
