I was cycling and at night I arrived to a hydro power dam. I asked them to allow me to camp somewhere around and they finally accepted but I couldnt find the right place to camp and it was totally dark. 
There was a guy there and I asked him if he can help me to find a place for my tent and after calling another person, he directed me to a building which was kind of abundant but still fine to sleep overnight. 
DUring our conversation, I realised that there is a school there and I can visit it in the morning. 
What a great chance to visit a school just like that.
