Have you seen this?

I've seen something similar to this but not quite as extensive near Sandusky, Ohio... Catawba Point I think.
 
Roadside America was written up in the first copy of Toy Trains I had. I finally got there 40 years later.
It's located in the same area of Pennsylvania as Hershey, Lancaster and Strasburg. The display has very much a 1950's feel, but in keeping with the Pennsylvania Dutch neighbourhood.
