The barb wire fence is around Pope mine shaft. Shaft is right beside the road. If a person was not careful they might drive right off into the shaft. The shaft collar is small enough that a pickup could not enter it but it might be interesting on a ATV. I would not like to try that. Maybe the air brakes would not work too well. Oh well, it is not the fall that hurts a person....it is the sudden stop at the bottom that does the harm.
