Maybe I am just not a very complicated person, but I am as amazed by jet travel now as I was when I was a kid. To travel over large expanses of the earth to go from one climate and one culture to another in one day still amazes me. I am always blown away walking out of the airport in Jamaica in the dead of winter, and always depressed when I walk out into winter when I get back. At the start of my trip I notice people being picked up to go home, always so sullen and quiet. Then near the end of my trip I watch people just getting in, all excited and going through the "get set up" routine. The travel experience overall is still amazing to me, I'm hooked.
