Where are the Trees?

I've visited a lot of new home communities, and I love them. But I do have one complaint.

The trees are often in a row behind the house, but there are no trees in the front or back yards, no trees that come with the house, itself. I love trees. And my realtor tells me that they can be added, planted in, but then you have to really baby and nurture them so that they live and flourish.

Seems to me they could leave at least one tree per lot? But since they didn't, maybe I will eventually add one or two.
