A little daydreaming can take your mind off the road.
I was driving on 8th Avenue and apparently forgot that I was in the middle of the Providence/Sacred Heart campus and some ongoing construction work.
Because when I saw a sign saying "Emergency Straight Ahead," I had a split-second of wondering "What sort of emergency?" and "Is it really still an emergency if there has been time to erect a sign?"
Then, of course, I remembered where I was.
