My friend worked the night shift at the bowling alley in Westchester, CA.  So me and my friends always went and played for free.  We would play 10 games a night sometimes.  My highest game I think was around 255 but I usually bowled around 170 to 185 or so.  But I did have a series (3 games) where all the games were over 200.  I used to be a scorekeeper in a bowling league at the South Bay Lanes in Torrance
