The appeal of Old Treehouses

Came upon an old treehouse today,

which flashed me back to my childhood.

I enjoy finding all Treehouses as they

have a sense of fun and adventure to them, but

 the vintage, abandoned ones always make me think.
I wonder what they did the last time they were up there?

Peeking through the fence we see the inside
of the Treehouse in its Winter state of non-use,
or maybe it's not used anymore, period.
