One change in olderlanes compared to newer ones is that the ball return subway is completely below the lanes instead of above. When I was a pinsetter mechanic, the subways were above, which meant having to lift the oiling machines over every one. Unbelievable pain the in the ass.

Bumper technology has also greatly improved and can go up or down depending on the active bowler. Back in my day, I had to put them up in the gutters by hand before a party started playing. Hated that.

Former pinsetter mechanic here! Once I was oiling the lane and noticed it was much harder than normal. Turns out, someone put a Cotter pin upside down, which caused it to dig into the lane. Boss wasn't mad at me but obviously wasn't happy about the situation.

What's a big mistake someone has caused at your location?
