I have been driving past this sign for several years. It is on Highway 29 South at Lovingston, VA, and it is probably one of the most symmetrical signs in the state.
Driving is very much a visual-spatial activity for me, and I spotted this marker driving alone to work. Nowadays my wife rides with me, and I am forced to partially inhabit the left side of my brain so I don't miss anything she says in case there is a pop quiz at a later date. Who knows what visual roadside wonders I am missing now?
