I can't stop watching this pic.twitter.com/FMV0UklWJJ— Ben McDonald (@Bmac0507) July 5, 2019

Seeing that thing throw that bowling ball will give me nightmares!
When I was 11-13 years old I set pins by hand - no machine.
We got paid 10¢ a game. We would always set two alleys, somethime 3 or four if shorthanded.
After the pins were set we had a small shelf behind the pit to crouch on while the bowlers bowled.
We were either on the shelf or jumping from one alley to the next.
A strong bowler can blast pins all over the pit and there was no way to dodge them.
They would hit us everywhere and HARD!
They'd leave bruises and sore spots - arms, legs back, head!
