In San Francisco, you cannot escape Pier 39 at the bay area. The Fisherman's Wharf at Pier 39 is a must-see place and well, as I said before, this is a tourist trap but hey, everyone is so willing to be trapped there including me. I love seeing the indolent sea lions basking under the sun on the floating raft. They make a lot of noise and gestures. They sure know how to catch people's attention.
