The back door of the treehouse at CNC. Beside the front door is a Shel Silverstein poem which reads:
A treehouse, a freehouse,
A secret you and me house,
A high up in the leafy branches
Cozy as can be house.
A street house, a neat house,
Be sure and wipe your feet house,
Is not my kind of house at all --
Let's go live in a tree house.
