Today on The First 40 Miles, pranking your trail buddies is fun, but it’s even more fun if your trail buddies are barely tall enough to ride a roller coaster. Then, we’ll share a wild Carolina swamp adventure that’s even too much for the British Empire. For today’s Backpack Hack of the Week, you’ll learn how to make a biscuit, quickly. And we’ll wrap up the show with a little trail wisdom from a Supreme Court justice on the trail, William O. Douglas.
