At one point, my daughter and I went to Mifflinburg, location of the buggy museum, to go to the supermarket. This sign was at the supermarket.
Across the street is a bank which has this sign and a parking area for horse and buggy for their Amish customers.
That evening, some went to Beaver Springs Dragway to see the Jet Truck. Are you getting the contrast between the buggy and the jet truck?
