When I was around twenty I started bowling on a winter league with my friends family, mom, dad, brother, sister, the full group. Truthfully I had a lot of fun even though I was hesitant to join at first. I was an OK bowler but lacked consistency, I think my average was in the 160s but was capable of bowling a 130, or on a good night breaking 200.
When we all had young families a group of us joined a parents/kids league, I enjoyed that more than the adult league.
