Colerain Bowl has a HS league on Sunday nights at 6pm. It's got 12 teams of 4 and there already have been 2 300's rolled in league.
Also, on Monday nights they host a HS Shootout where you bowl a 2 game qualifier, the field gets cut, then you bowl match play until there is a winner. You earn points for each week and each match you win. At the end of summer, scholarship money is awarded to the top spots.
Oh...and you bowl on PBA oil patterns. Right now, it's the Shark.
