This is a Blog about golf, mostly, so here's another golf post

More times than I can count, I'll be in the middle of a round of golf when all of a sudden my playing partners realize they're playing with the same type ball.  They find this out when they've hit their shots, and when looking for their ball they both think they've found their ball when they find one ball.  They didn't mark their ball before starting.  A necessity many of my playing partners fail to do.

All golfers should carry a Sharpie in their bag and mark their ball before teeing off.  This will prevent confusion at a later time.  You're ball can be marked any way you like.  Use your favorite color.  Draw a face, use your initials, or just use a dot or two.  This way, you can recognize your ball no matter what type ball your playing partners use.
