I've read information and other's recommendations on BOBs for years, now. Its easy to get too carried away and end up with some bag recommended by someone else filled to overflowing that a donkey would have trouble hauling. If you just graduated from Ranger School you will be able to hump 75 plus pounds and a weapon, but most of us don't fit that category any longer and maybe never did. We can't prepare for everything. Whats your most likely risky event? (I doubt its total societal collapse.) I wager that for most of us its some severe weather or other natural event that would cause us to temporarily evacuate our homes, or possibly maroon us in our vehicles or at work until conditions improve. So take the time to identify what risks are most likely in your area that may cause you a problem, then work from there in understanding what may be required of you in order to reduce the risk's impact on yourself and surviving it. Be realistic. If you are unable to carry everything but the kitchen sink in a pack, then having it sitting over in the corner is of no real use to you. Concentrate on those few items that will help keep you warm and dry in the conditions you are likely to encounter and adequately hydrated. Having a few energy bars doesn't hurt, either.
