One of the things that me and my friends would do is enter these gigantic drainage pipes and just wander on and on and on until we popped up through a manhole cover ages away from where we started. We were a different kind of fearless back then because that was definitely not a safe place to be.
you likely saw one of these death traps as a child. They were the best!
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.
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!
