Every tournament is a bit different. US Nationals pins stick up higher than Des Moines. In Minnesota, a drill is required to penetrate the permafrost. In my backyard, the pins stick up only slowly out of the ground (so I can mow over them). Depending on the way you drill kubbs or throw batons, the height of a pin can make a difference.
Should there be a standard height for pins? If so, why? What about safety? Should they be painted? What should the standard be, and how do you apply it?
