Kayakers are like surfers. They get started, and the next thing you know, other parts of their lives begin to fall by the wayside. They try to get you to go with them. And no finer kayak evangelist exists than Ted Choi of City Kayak; he has introduced many, many paddlers to the joys of the nighttime city skyline seen from the water on a full moon, among other vista beauties. But what about the upside-down thing? Do you automatically have to go upside down underwater if you get in the boat? Find the answer to this and other dumb questions at Choi's Downtown San Francisco Kayak Trip, which is suitable for inexperienced and/or clumsy mariners, although you should be able to do five push-ups. The one-hour course teaches the basics on a calm little inlet. If you ever want to see that night moon skyline, this is a perfect place to start.
