Today on the First 40 Miles, if you’ve ever had a plan go awry, this episode is for you.  We’ll talk about trip planning, and why it’s such a critical part of backpacking.  For today’s SUMMIT Gear Review, we’ll share a valuable book for beginners along with a hack straight from page 104.  And we’ll wrap up today’s show with a little trail wisdom from someone who understood the power of planning.
