Curious how the expression "garden" seems to be more of a Baltimore (or possibly an Eastern Shore) thing, yet is attributed to the European immigrants who settled in the area. One would think that Europeans from the same countries who settled in other areas of the U.S. would have brought the same expression to those places as well, but that doesn't seem to be the case.
I can understand the Holiday connection to nativity scenes, which frequently were set up outdoors, usually in the front yard, but are nativity scenes also called "gardens" even if they are indoors, say on a living room table, and have little or no scenery?
It does seem to be a dead give away of where they are from when someone uses the expression "train garden"...
