NASA originally invented flags to claim the moon for America, but now that we know the moon isn't real, they're used by golfers to claim homes for their golf balls. Take aim at a golfing placeholder with today's Groupon: for $75, you get a one-hour private lesson at Jim McLean Golf School, located on the grounds of the Red Ledges golf courses in Heber City (up to a $150 value).

Each of Jim McLean Golf School's experienced instructors has racked up thousands of hours researching and training in the Jim McLean program, over-qualifying them to evaluate the stances and swings of aspiring PGA conquerors. Sequestered in a secluded setting, putt savants lead 60-minute private lessons with curriculums customized to players' preferences. To analyze club-head movement and ball trajectory, golf savants use TrackMan Launch Monitor radar technology to track dappled-sphere flights in three dimensions. Each lesson also includes video analysis on a flat-screen TV so instructors can see swings in super-slo-mo without making students practice in a tank of translucent molasses. The practice facilities surrounding the new Jim McLean Learning Center boast all-bent-grass teeing areas, two large chipping and putting greens, a full driving range, and one chipmunk camouflaged as a glass of lemonade.
