I haven't been out of town in a long time and haven't seen signs other than "wash your hands."
There was one church sign that really made my daughter and I laugh. I was trying to get her to a new allergist and the GPS on my phone had me driving in circles. I am cursing at the map app, it is pouring rain and I can barely see the road. I see a church parking lot and pull into it so I can get my bearings. Caitlyn says "Jesus is your GPS." I snark back-- Yeah, funny! She says no-- that's what the sign says! The church sign did indeed tell me that Jesus is my GPS.
(I am sorry to report that Jesus was not able to help me find the Dr's office either. I had to stop and ask for directions at a convenience store)
