First you have to hunt where the animals are. You can contact your state biologists who will point you towards good places of habitat in your area. Preseason scouting is huge towards being successful. Rifle season tends to be more competitive than bow so numerous scouted areas are needed to allow you your own space. We are modern man, we walk like it and animals hear and know our sound and scent. You have to take measures to minimize both of these. Hunt into the wind, learn about thermals in the mountains and how to use them, deer and elk do. Listen a lot, cup your ears and pay attention to even small sounds. Learn patience, sit for an hour so the woods goes back to normal before you begin your slow "still hunt". Hunt every hunt as if you will be successful, by that I mean be prepared to properly care for the animal as in game bags, tarps, ropes, pack frames, saw, anything that ensures the quality of the meat. Hunt up hill pack down if you can. Carry a compass always and check directions before entering the woods, Gps's are great but can fail. Get topo maps and learn how to read them. In areas that are mostly steep locate those out of the way "benches", little flatter areas, again preseason scouting. Big bodied elk like them, deer don't seem to care. Learn to call, with so much info out there you will easily find the calls that work for the season and animal you are targeting, just use them wisely and sparingly. Over calling might work on a mad rutting bull but talking to guys who successfully call will help you recognize when and how. Lastly be a thinking hunter, your brain is your best tool, recognizing a situation and capitalizing on it makes for a happy hunter.
