Often I just go for drive, kind of like a "day" trip, just to explore. After I went to the estate sale I drove to a couple of cemeteries to look for possible relatives. In smaller towns, the graveyards are often just outside of town and the roads are often gravel. On my way back to the highway I encountered what I thought was a horse and buggy. Being on a dirt and gravel road, I pulled to side to let the buggy go by. I was curious about it, so I stopped her after she had waved and thanked me for pulling off to the side of the road.
She mentioned they go to Iowa. Here's a link I believe is the one she recommended to me during our "on the road" conversation.
