Hah! Not dumb questions from someone who lives in hill country; I, myself, am from Pennsylvania. Mennonite generally do not use horse and buggy, that’s the Amish. And being from where you are you wouldn’t necessarily know about things pertaining to subways.
That’s odd. I thought in Tennessee there was a fairly large Mennonite community, and when we visited, they were often in horse and buggies. Maybe there’s a mix? I see Delano uses both variations to describe the farmers market there.
