The three public washrooms here at Perry Lakes were all locked when we were there. Fortunately I was able to climb in or through two of them to get photos.
The wood in this photo is the entrance to the first washroom.
The third washroom was elevated about 7 feet up and was a lot harder to get access to sense there was no hole big enough to fit myself through. However I did manage to get my hand in there and take a photo looking up, which is basically what the view would be like.
