If you're new to the area or visiting SF, you really need to check out Golden Gate Park...Well...it's a lot bigger than any park you've ever seen...The place is huge with a variety of Museums and Botanical Gardens. It's definately a perfect place to just have a picnic or fly a kite. My personal favorite attraction is the Japanese Tea Garden. The place is peaceful and houses a number of Japanese plants and a Japanese tea room. The Shakespeare Reading Garden lives up to its name. I only wish I brought a book that time I went. There are parts of the park currently under construction, but there's definately still plenty to see and do.
