I'm obviously biased by the parks I live near and see/use every day, but when I think of a park, I think of tree'd sitting areas, tree'd play areas, tree'd walking paths, and some monoculture sports fields, with trees for the stands.

There are lost of community gardens around, but as a black thumb I don't use them and bias them out.

Basically my city has a hard on for trees in parks, and I'm all for it. I also think I've developed a bias that roads have no trees, and streets have trees.
