Is your backyard perfectly manicured? Nice short and trimmed? Mine isn't, I keep the lawn at about 3 to 3 1/2 inches, similar to the rough around most greens. Most of us if we miss the green aren't on a perfectly maintained section of fairway, we are in the rough, fighting to make a swing that doesn't exist on the driving range.
Let your grass grow and get some real practice in the backyard. Oh yeah, the grand kids like it long too.
