Many big cities will have a "State" st/ave/ln/pl/ct/etc. And I'm guessing a number of cities have a "Church" st/ave/ln/pl/ct/etc. And a few of those cities will have both. Now the question is, in how many cases do they intersect? I'm guessing photos of the street signs from those intersections could easily be used for social commentary both pro and anti seperation of church ad state.
