I added the scabbard and rifle to the pack, which upped the weight by 7#. #44 right now, and hoofed the 2.2 mile course without breaking wind or much of a sweat. My pack won't get much heavier until I have to pack a critter out. Less than a week before heading west. I will try to add some distance over the next few days, but just have too much else to do before we leave.
