Golf was originally conceived as a prehistoric-pest-ridding process to lure dimpled-sphere-hungry rats from cave dwellings into small bottomless holes, trapping them in free fall forever. Hone a rodent-harnessing hole-in-one with today’s Groupon: for $25, you get one hour of golf-simulator time for up to four people at Randy Henry’s Dynamic Golf School (a $50 value) at the Couer d’Alene Resort.

Randy Henry’s Dynamic Golf's aboutGolf PGA Tour simulator lets golf enthusiasts sharpen their skills in the middle of the most brutal lightning storm. Links lovers can practice swinging, slicing, and putting on their choice of 55 courses, including top-ranked courses such as Pebble Beach and Pinehurst, within the digitally rendered, high-definition world of a 180-degree panoramic screen. A new-fangled sensor array analyzes the weight and rotation of real-life swings by taking video and digitizing golf-orb statistics such as speed and rifle spin, allowing swingers to mathematically improve their whiffs. Once the ball is airborne, invisible cherubs transport the dimpled globe from this dimension into a parallel universe that is safely contained within the simulator by an ancient pact between Scotland Yard and the denizens of a second Earth.

While the aboutGolf PGA Tour Simulator has more reliable safety protocols than a holodeck, it is just as popular, so call ahead to reserve your virtual tee time.
