Overton County, Tennessee Roadblocks

These are often found between Union B Rd and Muddy Pond Rd. My wife and I own wooded property up there. Last summer we traveled individually a few times in separate cars. Sometimes I was the car in the line stopped, and she allowed through without stop. Other times she was stopped and I allowed to go on without a stop. She was always asked about her marital status. It also seems to roll along up and down the road, and from one area of the county to another. Though here it is fairly common.
