Like suntans and the ability to throw knives at apples on top of totem poles, golf skills disappear if you don't keep working at them. Keep the magic alive with today's Groupon: for $15, you get an hour of golf in an indoor golf simulator (up to a $30 value) at Play 18 Indoor Golf Centre on Albert Street. Play 18 Indoor Golf Centre is a newly renovated, climate-controlled retreat for golf enthusiasts with 38 simulated courses to choose from, as well as a driving range. The nine state-of-the-art simulators use 3-D graphics to re-create realistic courses and effects such as trees swaying gently in the breeze, the sound of balls dropping into water hazards, and sentient golf carts heading for the hills. To refuel after an energy-expending round, Play 18 offers a menu of drinks and snacks to enjoy while catching the day's sporting events on the 110" big-screen TV.
