Have you ever built a tree house or known someone who has?

I was watching this video about some tree houses in NYC and was remembering my friend’s uncle’s property.

They had/have a tree house and some platforms around their yard with a zip line and some other fun things, like a bridge over a stream and target buckets in a small pond to toss ping pong balls into from one of the the platforms.

Another friend built a pirate ship for their son to play on in the yard. In a way, it is like lawn art too.

Does anyone else have experiences like this?
