Bowling was invented during the Industrial Revolution when unsatisfied workers would hurl bowls at their bosses, and then strike when the bowls failed to come back filled with stock dividends. Unionize your league for some collective bargaining on the lanes with today’s Groupon. For $6, you get three games of bowling ($3.95 each) plus shoe rental ($2) at Gilmore Lanes in Fairfield (up to a $13.85 value). A polished palace of ten-pin punishment, Gilmore Lanes earns bowling bragging rights for its friendly staff including three Hall of Fame bowlers (one is a Hall of Famer in the state of Ohio, two have been canonized in the Greater Hamilton Bowling Hall of Fame) who are on hand to pass on the secrets to a successful game and proper beehive coiffeur. Computerized scoring and closing times of midnight or later seven days a week make it easier than ever for players of varying math skills and negligible watch ownership to squeeze in some lane practice, though it may be best to call ahead, because open bowling times can vary.
