I hunt them in Northern Maine and New Hampshire and the only suggestion that I can make is be a tracker. Ususally the mountains means no crop fields or apple orchards. The deer are different there and you need to hunt them by tracking if there is snow. The rut plays a major part and that is one way to see the bigger mountain bucks. I like to still hunt along swamps in the saddles between the peaks. The deer aren't usually going to be found in the sterile hardwood ridges. Stick to the thicker stuff below the peaks and you will find deer. You get one in the mountains and you earned it. Good luck.
