### Instruction: What should I do this spring in San Francisco?
### Response: During the spring time, people in San Francisco enjoy visiting the parks for the cherry blossom, check out the open markets when the weather is nice, and explore the Golden Gate Park. If you want to venture farther, you can enjoy the wildflower festival in Half Moon Bay, take the ferry to Sausalito, or even spot Humpback whales in the Bay Area!
