Similar thing happened to us Wednesday. High series was 640. There was one more 600 and more 300 and 400 series than 500s. I shot 563-167,192,204.
The 125 a average bowler on our team started out with his highest game ever, 247, and ended up with the 4th highest series in the house, 587.
The guy with the second highest average in the league, 215, is also on my team. He wined all night and shot 430.
This is a tough old wood house that has given up only one 300 and 0 800 this year. Still, there was almost a protest when bowlers found that there was no hook, no backend and the only way to get to the pocket was to bowl straight at it.
