The phrase "chip on your shoulder" takes on a new, life-threatening connotation when muttered on the golf course. Save your shoulder for the swing follow through with today's Groupon: for $40, you get 18 holes of golf for two and cart rental at Birkdale Golf Club in Chesterfield (up to a $90 value).

Birkdale Golf Club is a semiprivate golf club that courts novices and masters alike on its par 71, 6,630-yard course, proffering a mix of risk-reward holes and four sets of tees on each for varying skill levels. A green sea of verdant trees stands vigil around the Bermuda grass fairways and bentgrass greens, gently plucking wayward balls from their branches and returning them unharmed to the clubhouse for dimpled cosmonaut training.

Players can practice all aspects of their pendulum pulchritude at the driving range, putting green, and short-game chipping area. The courteous and welcoming staff sets daring drivers up with their own carts, affording players the leg strength for their eventual victory jig or defeat shuffle home. This Groupon is redeemable anytime Monday–Friday, and after noon on Saturdays, Sundays, and holidays.
