Something we've all been tempted to do as the kids get older. Maybe 2 or 3 bricks! Of course as they get capable of carrying more, Mom and Dad get to carry less, which also helps a bit. Of course as the kids get older, they require more food! Last backpack I took my teenage grandson on, he carried all his own gear, all his own food, and part of the shared gear. Next time we go together, he'll get to do most of the driving to and from the trailhead, too!
