Joyous sounds reverberate off the walls at Mason Bowling & Recreation Center, a decades-old entertainment emporium managed by a staff committed to keeping its guests entertained. Pins clatter on dozens of lanes designed for candle-pin bowling, a variation on tenpin bowling that uses smaller balls and cylindrical pins that are not cleared away between frames so bowlers can hear their faint screams. The staff engineers the fun activities, hosting open bowling, overseeing league competition. On several tournament-size tables, billiard balls clack against one another, and in the onsite arcade, video games bleep and purr like robots napping on magnets. In warm weather, the staff unfurls an 18-hole miniature golf course and opens an onsite sweets station that serves freshly scooped ice cream.
