I like airports. they are the best for people watching, people coming and going to points across the globe.
Air travel is still magic. I can flap my arms all I want and I can't fly without a plane. There is the majesty of the machine and the quickness. Journeys that took my grandmother a week 100 years ago. I can do today in 6 hours.
I can't believe how cheap air travel is. I can't put gas in my car for what this trip cost by air. Yes airfare has gone up and it is harder to find a bargain, but there are bargains to be had if you plan ahead.
I like traveling. I wouldn't do it every day. Interesting hypothetical question. If air travel was free, how much more would you really travel?
