I stumbled into the Four Corners idea when I was trying to find a way to illustrate neighborhood diversity in small towns. I discovered that frequently, if I was diligent, I could find intersections that evoke character and often a sense of history.  I did not always find the neatest, cleanest, most curious, biggest or smallest but they are interesting.  Neighborhoods have unique individualities where nearly every house has a different designer, every owner has a color scheme, and a particular concept of landscaping and maintenance.  The project quickly took on a life of its own and I now look for interesting intersections in cities of all sizes.
