There are some maps that show our road going through and some GPS's that also try to take some people down in. At the end is a nice big sand pit and there have been some vehicles that try to drive through the sand and of course get stuck. Hubby has pulled some people out of the sand but not any more. The sign says Dead End and if someone is stupid enough to drive up our road and get stuck, they can call a towing service.
GPS is fairly useless in getting to my house, too. I give everyone directions, but they think they know best and follow their GPS, invariably having to call and ask where they made a wrong turn. I have to remember to tell them NOT to use GPS.
