First off, if you cant get to the course it doesnt much matter how you shoot right?
But, im assuming you plan on getting out there again and dont want to learn how to swing again on the course, so i would suggest getting a backyard mat and netting system and just hit balls while your kids are killing each other...hahaha
However, be careful on what you buy b/c i destroyed one in about 30 mins. I have a 120 mph clubhead speed, so i would try to find one that will definetly work with yours or it will be a waste of money.
Oh, and putt on a carpet...thats very important as well!
Hope that helps!
