When I was little, I used to see "Hidden Driveway" signs and believe that they had been specially hidden for alert people to find, like Easter eggs or a game of Where's Waldo. So I was always very excited to see "Hidden Driveway" signs and look for the hidden driveway. After my sister informed me that the signs were just there to warn drivers about the driveways being hard to see from the road, I was pretty disappointed, and a little more magic went out of my world.
