One of John Boyd's better known contributions to the world is the Observe - Orient - Decide - Act loop, also known as the OODA Loop. It's become a pretty important concept, for both business and military strategists. I ran across an actual OODA Loop while driving on Maxwell Air Force Base, in Montgomery, Alabama.
Being the Boyd fan that I am, I naturally had to turn my car around, find a place to park, walked over with my camera phone, and snapped this picture.
Finding this street sign was, hands down, the highlight of this trip.
