Collector’s Weekly did a good article a while back featuring the rocket slide:
The one pictured in the article is near my grandma’s old house in Colorado, which I used to visit as a kid. The park with the rocket was too far to walk, but I could bike there on gramma’s adult-sized bike.
I could reach the pedals, but not the ground, so to stop and not tip over, I had to swing off the bike and jump my feet down to the ground. That didn’t always work out (still have scarred up knees from that) and so just getting to the park was a thrill. Then, I would climb to the top of the tower and feel it sway, and be so overstimulated I would feel faint. Then, back to grammas for raw hot dogs and piles of candy. Good times!
