My(our) set up not quite that bad. Alley had 8 lanes but unlike this one, had a shield in front.
There was an opening between 1/2 etc so pin boy (DON’T CALL ME BOY) could shuffle between both lanes...pins flying all over the place and buttheads throwing while in the pit...had a pretty good arm and lofted more than a couple pins over the top of frame.
Only caught one betwixt the running lights once, they were ALL scared to death since I was so young...shook it off but they made me fill out tax forms etc to sort of make it ‘legal’...so I have a FICA witholding from 1954...
I did put a derelict or two out of an honest living.....HA...
One of my very first *dates* was with a macho guy in HS that was on the football team .... he took me bowling. I recall, he tried to wing the ball so hard as to try to *mix-up* the pins, so they would fly around and hopefully hit the *pin-boy* ....I didn’t think that was funny. I never saw him again, what a jerk.
