Most of that little ("just because it might possibly happen") stuff you can leave behind. You unnecessarily complicate life by trying to prepare for any contingency that has a less than 0.1 percent chance of happening--the Chicken Little scenario. In most cases you can improvise! Last summer one side of my hip belt buckle was missing at the trailhead, so I just removed the other side and tied the belt ends in a square knot. It worked just fine. If you break a tent pole, you can usually fix it with duct tape (do take 2-3 feet of that; it's also for first aid and other uses). If not, there are usually sticks around. The same is true of tent stakes. With the sleeping pad repair kit, which usually contains enough for several patches, just take enough for one.

Just make sure you have your "Ten" Essentials with you and you can survive most anything.

Do coordinate with the rest of your party! While there's no need for each of you to carry 50 feet of cord, you do want to make sure that at least one person brings it!
