I once was traveling by ferry boat from Juneau to Sitka Alaska on a very stormy sea. The ferry was one of the little ones and it pitched and rolled unbelievably. I really admired that little boat though, it just plowed on.

Anyway at one point I was in a lounge chair on the outside deck watching the noisy waves come crashing in and sluicing down the deck. Sitting there and wondering what would be the first indication of seasickness I suddenly was reminded of what the action reminded me of: a galloping horse.

And no one gets seasick on a galloping horse. I was fine.
