I have just survived the hardest hunt of my life, four and a half days of chasing elk in the Swan Range east of Missoula, Montana. I've never been more tired or sore. I was hunting with guys who were all at least 20 years younger than me and longtime elk fanatics. Guys like that aren't just in better shape than the rest of us. It’s almost like they’re a different species. They walk fast all day long and don't particularly care where as long as it's up. The steeper the better. They look at a pass 5 miles away and 3,000 feet higher and say, "That looks elky." At any moment what they are hoping for beyond all other things is to add 120 or 130 pounds of meat to their packs, hike back to the trailhead, turn around, and hike back up and down by headlamp carrying another 120 or 130 pounds.
