I have a buddy that had a 300 ring in HS, but I graduated back in 90 so maybe it was actually cool back then.
My high game was something like 202 (I pretty well suck).
I remember my dad taking out a 7-T split once without seeing the pins go down. He was basically pissed, and just threw the ball and was walking back to his chair when the 7 hit the 10.
