When I was a kid, putting aids involved lining up the words on a golf ball with the intended line of your putt. Now we have 2-balls, 3-balls, and lines on our golf balls. Tiger draws his lines free-hand, but he does a lot of things that the average human can't do. Some people are willing to spend up to $9 to help them trace their lines. What are they thinking?

The Grouchy Golf Blog has taken matters into his own hands and creatively developed his own way to trace a guiding line on his golf ball. Using a gatorade bottle, something you can find on any golf course, he's solved his problem, quenched his thirst, and saved a few bucks.

The pictures describes it all, but for the actual blog post you're gonna need to check out the Grouch Golf Blog.
