The weird thing I saw in the past week:

In Hawaii, they have these little scooter cars with one rear wheel and two front wheels. They're red, and egg shaped, and have a little black rollbar. As I was waiting for the airport shuttle outside my hotel I saw one of these come whining up the street with two really big, sunburned American tourists hanging out of it. I wept because I didn't get a picture.

The other weird but cool thing was seeing 60+ surfers with long, graying hair, heading down to the beach, walking through the waves of tourists, carrying their boards.
