Maybe it's because in a lot of the country, there are a lot more trees
per acre in the urban areas than in rural! 

Really, have you noticed how in a lot of the major agricultural areas like
the midwest, rural areas are more and more planted out to the shoulder of
the road, without even a fence?  When I lived in Wisconsin, I heard a lot
about this trend.  Around here (Boston), the best place to go to see lots 
of trees is in the ring between I95 (route 128) and I495, in other words, 
the high-tech suburbs.  Farther out, there are occasional woodlots separated 
by fields.

Of course, in California, the cities are about the only place you'll see
any trees at all.
