It's a very common site and greatly increases the value of the property.

It reminds me of when I was telling my Canadian friend how my pool gets a lot of leaves in it from all the trees and they said that was unfortunate. In Austin the pools get too hot to actually swim in if they aren't shaded.

Depends on the city. Here in Atlanta we are a "city in a forest" and for older neighborhoods with mature trees it's more common than not.
