Today on The First 40 Miles, what happens when thousands of outdoorsy people get together in one place? A city full of happy and healthy people. Then, on today’s top 5 list, we’ll share the top 5 themes that have tree-huggers, peak-baggers and hill-hikers all excited. Next, on the SUMMIT Gear Review, you’ll find out which knife replaced the heirloom that Josh has been carrying since he was a scout. On the Backpack Hack of the week, you’ll learn how to use your fuel can to track fuel consumption. And we’ll wrap up the show with a little trail wisdom from our good friend on the trail, again, Mr. Emerson.
