I sometimes mentally count up the weight in some of these supposed emergency kits, and 80 to 100 pounds is not unusual.
I am not opposed to having a firearm as part of your bug out equipment, but having 40 or 50 pounds of guns and ammo makes little sense to me.
Its not unusual for these bags to have 10-20 pounds of MREs, and 10 pounds of knives and axes and other tools.
I often wonder if these people even really have such a bag. Who is thinking that carrying 100 pounds of crap on your back makes any sense?
