I wish I could find it, but somewhere I have a photo of a sign a neighbor of ours had. It was basically a small version of the basic green, reflective highway signs (like in NR's pic), but said "S. Smith next four exits."
You had already been beating down a number of miles worth of Sandhills county road and crossed a few autogates before you ever saw his sign, and the four "exits" were his driveway, the shop's driveway and two windmill trails. :lol:
