Let's list here the options available to HS bowlers this summer while waiting for the new season to begin.
Colerain Bowl has a High School Shootout every Monday starting at 6:15. You bowl 2 games of qualifying and the top 8 advance to head to head competition. It's single elimination, and you earn and accumulate points all summer long. The top point earners receive scholarship money. I think it's only $10 each week and they put out a professional pattern for competition.
Coaching is available during the shootout, as well.
