Before golf was invented, grassy pastures were viewed as the exclusive territory of roaming sheep, herds of cattle, and overzealous Civil War reenactors. Celebrate turf's competitive utility with today's Groupon: for $80, you get an 18-hole round of golf for two with a cart rental and two buckets of range balls at The Monster Golf Club in Kiamesha Lake (up to a $160 value).

Named one of America's 20 most-difficult courses in 2010 by Golf Digest, The Monster Golf Club's notorious holes stretch a colossal 7,650 total yards from their Monster Tees. Monster's architect brought the PGA-caliber links to life in 1963, though professional golfers still refuse to play a tournament on the course due to its daunting length and invisible grizzly-bear pits. Water obstacles demand golfers’ focus on nine of the holes, and several par 3s force shots to carry over water from tee to green. The par 72 course winds by a variety of natural scenery, from woods and glistening streams to rolling, elephantine greens and sand traps hosting life-size dioramas of The Iliad. Gameday golfers receive a cart for cruising the majestic fairways and two buckets of range balls for noncompetitive smacking.

The Monster Golf Club’s rates fluctuate throughout the season.
