Hmmm, no option to vote for over 60 Lbs... So, I picked the 50-60 range. I am usually taking one or two kids with me on a three day hike, and though I pack to be under 60 pounds, by the time we hit lunch on the first day I always seem to be over 60. In 2000 I think I hit 80! Ugh.
There is always someone in our group that manages to shave yet another five pounds off of their pack from last year. Either with newer fancier gear, or just not taking something they used to. There are even a few that lighten up by losing blubber, myself included.
But with kids on the trip, I never cut short on the gear. I just can't tell what I may need on the coming trip and don't dare to get caught without it. And kids eat a lot. Better safe than sorry.
Community gear doesn't impact my load much. With two kids the three of us qualify for our own filter and stove, etc... So I carry the stuff I would want the three of us to have anyway. That way, the kids and I can bail or take a shortcut out without impacting the whole group. Though in four years we havn't had to yet. And pretty soon the kids can start carrying my gear for me, right?
I don't know if any of this helps, but what the heck. If I decide to be a lighter hiker, I try to shed pounds from my midrift, since that is the weak link... I still have at least 20 extra pounds there.
