Any of you guys use ammo cans as B.O. cases? I have a couple plastic cabela's ones packed with canned goods/firstaid/ammo/misc gear. As of yet, I don't have a duffle dedicated to bugging, but maybe I should. I doubt they are REALLY watertight, but I think they are close. Only problem is that they can get kinda heavy. Are you all more in favor of something with a strap?
