There is a historical military base less than two miles from my house. Lately it has been a hub of activity because there are numerous Stops, Gyms, and of course Pokemon throughout the buildings and walkways. 

Which appear to be embraced. We took a walk today to see all of the gamers and came across some great sidewalk chalk art. 

I know some people roll their eyes about this game but things like this make it a thing of beauty.
