I used to live on Bainbridge Island which is a 35 minute ferry boat ride from Seattle. Normally its a pretty smooth boat ride. One winter though, we had a wind storm that lasted for 2 days. On the second day I took the ferry boat into Seattle - what a ride. That trip over to the city was a little rough, check out the video.
