The sunset cruise started from waterfront. After a closer look at those international shipping ports and a wonderful view of Mt. Rainier (yes, it is out for yet another day!) from Puget Sound, we finally went towards the famous Hiram Chittenden Locks and sailed in Lake Union. The lock connects the sea water from Puget Sound and the freshwater from Lake Union, and it functions pretty much like a water elevator, which reminds me of the Gezhouba Dam (葛洲壩) on the Yangtze River. There are quite some beautiful houses near the lake, and one of them was actually where Tom Hanks lived in the movie Sleepless in Seattle. Got to admit that with such a nice lake view and those lovely little houses, how can Seattle not be a romantic city!
