I knew an old guy (90 something when I met him), who had probably 70 or more sets of just monster elk antlers hanging in his huge shop. Those were just his personal ones, he was an elk guide most of his life. I have had more frustration hunting elk than you can imagine, and so I of course asked him how he did it every year like that.
He said it's really easy. You own a couple of good mules. You ride up to the highest mountain you can find in the area, where you can survey the country with some really good binoculars. You then pick the deepest, darkest, nastiest hole you can find, as in, the one that makes you shudder and pray to God you never have to haul an elk out of that hole. Get back on the mule, and down that hole you go, and then shoot the first big ass bull you see when you get there (because there will probably be more than one).
Hard to say how much of that was an old dude poking fun at my sorry ass who's hunted elk for 20 years and only killed a few (none of them very big), and how much was legit good advice, but he seemed sincere.
