Not much I can add, I think that everything has been pretty well covered. I have no doubt that next time you have to bug out you will take the bag you made up for that very purpose. I would really suggest that you get a light of some kind, little bitty, mid sized, something, and carry it on your person ALL the time. Next time you might have to abandon the BOB and hit the stairs, lose power, emergency lights in the stairwells (if they are installed at all) can fail, and it can be DARK inside of those things. I recall reading of one guy (who died in the process) with a light who kept going up and down the stairwells in one of the towers on 9/11, guiding people out because there were no lights...
