Golf is considered a gentlemen's game due to its emphasis on proper etiquette, color-coordinated outfits, and the removal of all brass knuckles and inflatable billy clubs before competition. Refine your sportsmanship with today’s Groupon: for $20, you get five large buckets of driving-range balls at All Sports Dome in Auburn Hills (a $40 value).

Golfers at All Sports Dome take aim and slice at the dimpled orb year-round with indoor and outdoor driving ranges. A day’s worth of practice swings awaits with five large buckets brimming with spherical missiles. Customers launch orbs indoors between 9 a.m. and 4 p.m., whereas practitioners outside begin at nine but pierce the atmosphere until the last visible rays of sunlight disappear over the horizon or are extinguished by a concerned cloud-welling giant.
