Oh my lord that thing is amazing. Haha! Of course I was the kid to climb up the outside of the structure just to make it a bit more dangerous.

enter these gigantic drainage pipes

I didn't realize other kids were doing this. Whenever I would find any kind of large pipe I would crawl into it. I would convince my little brother to follow me in and we'd end up up halfway across town sometimes popping up in surprising places. I guess we were the original Ninja Turtles hanging out in the sewers!

I remember when they started putting metal cages over the entrances and wondered why. I never considered that other kids were going in there. I never came across any. Maybe it was to stop me!
