Today on the First 40 Miles, Heather is back from the Outdoor Retailer Show in Salt Lake City with tales of what she saw!  Next,  today’s SUMMIT Gear Review features a buttery soft, ultrastrong + ultralight hammock.  For today’s Backpack Hack of the Week, you knew that a hammock had to do more than just rock you to sleep—and we’ll confirm your suspicion with today’s hack.  And we’ll wrap up the show with a little trail wisdom from a guy who has some wise insight about backpacking.
