I've always heard us being referred to the Duck Tales generation, but this tracks. Born early enough to skin your knees on a Big Wheel in the 80's, but only after Gen X had skateboards.
We had a slide like that in elementary school, except it had dual slides. You'd climb up the center and go either left or right, and it was two HUGE metal spiral slides.
One day, 8y/o me thought it'd be a grand idea to take a roll of wax paper and hand it out at the top of the stairs. 20 minutes later, I'm in the principals office, explaining why i did what i did, as kids are flying of of the top of each slide in the background...
