My get home bag is one of the civilian Camelbak packs, the Alpine Explorer. My major concern on a long walk is water and this one has both a 100 oz bladder and room for a liter bottle and water filter -- sources my be tainted. That will get me part way if I need to walk. If stores are open along the way I'll buy water as I go.

I don't plan to carry a weapon, just stay on major streets and walk with a purpose. No E&E intended.

My gut is that you won't be able to go unnoticed and if you try to hide it will make folks wonder why. Just go for the "more trouble than he's worth" look.
