Golf, like smiling and estimating the amount of lint on your T-shirt, is better done under a black light. Reveal your wardrobe's late-night dryer trysts with today's Groupon: for $9, you get 18 holes of glow-in-the-dark mini golf for two people at Putting Edge (up to a $19.50 value), located in the Colorado Mills Shopping Center in Lakewood.

Putting Edge provides a phosphorescent indoor mini-golf course that is fun for all ages. The 18-hole course features challenging twists and turns amid a glowing battleground seemingly created by a doodle-crazed ogre with a highlighter and artistic vision. Upbeat music adds to the fun as you expertly navigate your way through the incandescent irrigation routes and prove to your date that your putting skills are untouchable, like the bottom of Bluff Lake or Celine Dion's hair.

Putting Edge makes an ideal playground for birthday parties and group gatherings and also offers an arcade for showing off joystick skills. The glow-in-the-dark atmosphere encourages fun, healthy amounts of competition for the athletically avoidant and a chance to see what life on Mars is really like.
