Kim invited me to swim with her and her friends: Miguel was a great kayaker guide for us, and Antonio (who is a is a super accomplished open water swimmer). We had an awesome time swimming along the Embarcadero all the way to the Bay Bridge and back. My favorite parts were when we stopped and chatted with tourists as often was we could at Pier 7, Pier 23 Cafe, Pier 39, the Ferry Building—and we even swam under the Exploratorium! It was an incredibly fun swim!
