Ideally, that’s how I would hold my gun in the grouse woods, too: at a sort of low port arms position. However, holding a gun while walking through wide-open fields and holding a gun in the grouse woods are two different tasks. Good grouse cover is thick and full of inconveniently placed young trees. No matter how ready you try to be, there will come a time when you are tangled up in brush, or behind a tree, or holding the gun in one hand while pulling a stick out of your eye with the other, and a grouse will flush. It happens. The only thing to do is to tell yourself that such occurrences are part of the fun of grouse hunting.
