Like a batch of crop circles, golf transforms open fields, precision, and low-flying objects into popular tourist destinations. Enjoy close encounters with today's Groupon: for $55, you get a round of golf (a $65 value), a cart rental (a $20 value), a lunch voucher (a $5 value), and unlimited practice-facility use (a $20 value) at Blackstone National Golf Club in Sutton (a $110 total value). This Groupon also grants customers a 10% discount at the pro shop.

Host to the Golf Channel's Amateur Tour, Blackstone National Golf Club's Rees Jones–designed course boasts nearly 4 scenic miles of manicured fairways and white-sand bunkers. Golfers can strengthen their stance before the game with unlimited use of the practice range, equipped with nine holes for stashing surplus corn niblets. Club wielders can then explore the greens with an unlimited cache of balls in tow, sharpening swings across 18 holes or softening cartwheel techniques across fluffy patches of grass. Each cart sports a GPS system that offers not only an electronic scoring system but also relays the distance between cart location, pin, and the nearest sandpit-castle-building contest.

After a satisfying hole sinking, golfers can retreat to the club's locker rooms and showers, then emerge refreshed and ready to apply a $5 lunch voucher to the National Grill. The casual establishment features a menu of Blackstone chili ($4.75), tuna-salad sandwiches ($8.25), and other hearty eats. As the sun sinks beneath the horizon, linger over a cold brew on the outdoor patio while discussing the pros and cons of using golf balls to plug dams.
