Mark Your Lie! The Mini-marker is an important, albeit under-utilized part of the game in casual play. The mini helps ensure that you mark you lie accurately, and helps to develop the habit of doing so in tournament play, where a costly penalty will be assessed if you fail to do so. The mini is also a great way to help support your local club. At $5, they're easy to pickup. Grab a few so that you always have one handy.
