Is the third shot really a floater or flier?
What does a 10-shot group look like or what kind of group do you get by overlaying multiple 3-shot groups?
Go to the SD website and look at the archery deer application for when non-residents can hunt deer on public land and that will help your decision given the dates/time frame you are wanting to go.
That's a nice 'lope.
The first cut I make is from the back of the head right through the mane on the back of the neck, and then follow the top of the spine to the tail. Cut around the knees, then up the back of each leg. Then start peeling the hide off as you do the gutless method.
After...
During the day the bucks will be cruising or bedding along the top 1/3 or so of those ridges to catch rising thermals or be in the thermal tunnel. You need to move up and be on the leeward side of the ridges. A mobile setup is the way to go.
