It's a poets walk with neat little signs telling about the spots, like all the hillsborough trails.
Go off the highway go into hillsborough and go till you see the bbq place take right go past highschool. Until you reach the foodlion, take right at light then go straight on the left you should see a memorial plaque with Mount Airy on it. if you pass the elementry school, you've gone too far.
