San Francisco is an interesting place. Back in San Francisco, use Google to navigate past before the rental car is returned. It's not very far from downtown San Francisco. It's about 20 minutes'drive. Parking near this street was very inconvenient. After several laps, a parking space was found two blocks away. The Hippie District, once a symbol of American freedom, has now turned into a distinctive commercial street with many strange shops selling animal specimens, medieval clothes and horror-themed items. It's fun to just look at the window decorations. Although there are not many hippies in the street as before, we can also meet a few when we walk a few steps. We even meet three men who are walking in the street. They should be frequent visitors in this street, because after a few steps, they will stop and greet the people around them happily.
