One set I run across is located on US40 near Tridelphia
Their story and how they got their is an interesting one.
They where put there by Rev. Bernard Coffindaffer who was from Craigsville West Virginia
He originally wanted to have at least one set in every county of every state.
I saw him talking about this in a CBS evening news piece as they where following him and his crew erecting them some where in US.
Supposedly a local church was to adopt and care for them,but many have fallen into disrepair while others have been faithfully maintained one such set is near a church in Franklin Twp . Pa. in Lawrence County.
