The mat goes on vacation with us. True story, my DD was around 9 and could not line up in front of me, so I put a stick down on one side of her and a pine cone down on the other side of her to mark the rubber. My wife made a swoop with the riding lawnmower and ran over the stick and then made a circle and ran over the pine cone. i went inside and ordered a mat and then mowed the grass. It saved a marriage and is a great tool for pitching.
