There's a metal slide on Belle Isle that costs $1 to ride. It's been there since 1967, but it closed in 2020 and just reopened with a fresh coat of wax.
There are four big bumps you go over on the way down. Kids AND parents were going so fast, they'd ramp off each one and land really hard. So it had to be shut down a few hours after it re-opened.
Luckily, someone got a few videos before they scrubbed the wax off! Enjoy!
