One of the things I like most about visiting family in TN are the loose dogs. I have cousins who between them and their folks had about 50 acres, with 4 houses spread out on the land they owned. There was always a few dogs running around. It was a rural-ish area. When my dog is outside I can't relax. I leave one of the entry doors, out to the enclosed patio area with another door, open so I won't forget he's out there. But in TN... the dogs are just around. You leave some food out for them, they'll eat it when ready.
