Part of Johnstown ATV Club's Edwardsburg/Cardinal Series of Caches
A series of caches in Edwardsburg/Cardinal, located on some of the unmaintained road allowances used by the Johnstown ATV Club to make up a network of trails used recreationally by ATV's. These trails are groomed in the Winter.
This appears it may have been an old playground/fort away from home for one of the neighbouring farms, as you can see a tire-swing hiding in the forest.
Not sure I would trust the swing today, but someone had a lot of fun with it during it's prime!
