I know enough physics to believe that flying can work, in theory, but it still seems almost magic that I can get in a tube of metal and fuel, and feel safer than in a car, and take off on a snow squall and in a few hours land in a desert. See videos 1 and 2.
Video 3 looks like a cartoon to me, and suggests we are not the only people who thought Mexico could be fun in winter. Believe it or not, within 30 minutes we got through this immigration maze, got our luggage, went through customs, and were on our bus.
Also, the nice customs lady asked me to push a red button. I did. Nothing happened. Then she told me we could go. Huh.
