DIY Raised Fort

This is a raised fort that was built by Dad and me a long time ago. It has a trick door and a secret entrance. The ramp was originally designed to raise and lower, but the mechanism was 100 cranks for 1 inch of raise. That would be 12,000 cranks to fully raise it! The fort is raised 10 feet off the ground. Any pictures I find of it being built I'll post. The secret door looks like a wall, (The wall on the right side of the door) but when pushed, it opens. It locks from inside with a deadbolt.

We would sleep in here with friends over, and Dad would come out and start scratching the walls and banging on the windows. Good times.
It also was the center of a lot of Airsoft battles, until I built the Airsoft course Hunter's Run in the woods. Most of the attack and defend battles were boring, because the defenders would lock themselves in the fort, and nothing could be done to get to them. The floor is covered in BBs.
