I am only piping up because I am curious about your intended use for a pack that can carry 100 lbs. For many of us, a 100 lb. load could carry enough food and gear for roughly 40 days without resupply.

It is possible that your mission can be carried out better by a packboard than a pack, but I'm just speculating.

So, whatchya gonna do with this pack? I'm dying to know!
