I am in no way an avid golfer, so I won't go into extreme detail about Markham Golf Dome. They give you exactly what the name says; a dome in which you can golf. That being said, it is a rather large dome, so you do have the ability to really get a feel for the potential of your swings.
One of its notables are the ground and suspended targets that they've set up for accuracy practice. And of course, there's the ball retrieval cart that comes along every now and then that you're obligated by law to hit.
For two hours, and unlimited balls, I shelled out $35, which according to my buddy, isn't bad. But hey, what do I know about golfing rates.
I should say that I get the feeling that an avid golfer would give this place a 4 star, but I'm just going by personal feel.
