Cover. Cover. Cover. It's all about the right cover. You have 2 options: 1. Read up as much as you can, get in the truck, hit the woods, and try and apply what you've read. This will take some time (maybe even a few seasons) to zero in on what you're looking for, but it's pretty rewarding when it all comes together. 2. Tag along with someone who is experienced, or hire a guide. Once you know what to look for, you'll be able to quickly identify productive cover, and not waste your time working poor or unproductive cover, and your dog will pick it up much faster as well. I took a old college buddy out last fall who had never hunted grouse, and by the afternoon he could ID good looking cover like he had been doing it his whole life....something that took me seasons to figure out trying to go it alone.
