There were 12 us riding in South Korea a few years back. We came down a long hill coming out of Kunsan City. We were lined up single file, I was pulling, we caught a Korean fellow on a scooter. His Scooter had huge mirrors on it, but he didn't notice us at first. We got on his tire and hung on there for awhile before he realized he had company. Because his mirrors were so large I had a very clear view of his expression when he finally realized we were on him. It was pretty funny, his eyes got really large, then he tried to speed away, but we hung on. We stayed on him for at least 2 miles. He finally slowed and turned off our route, we Americans saluted him and loudly thanked him "Comsamneeda!" It was good.
