How Do You Get Your Green?

My participation in this year's Park(ing) Day has really got me thinking about the lack of green spaces in urban areas. Growing up in the country, it never really occurred to me that some people just don't have access to the green grass I was so tangibly familiar with. While there are a handful of wonderful parks in San Francisco to visit, including the vast Golden Gate Park, they simply can't compete with opening your back door to a canopy of trees and plants. Tell me, how is it that you get your fill of green space?
