I guess I see this a bit differently that those posting so far. I don't think this is such a good idea.

For me (EDC and PSK aside) a BOB is just that... a Bug Out Bag! A bag with what I need to make it..(and the lists posted could go on forever..) and kept where I can grab it when I have to bug out. Fire, flood, invasion of the living dead, etc. One bag. Grab. Run.

My objection to a BOB and a grab and go (which I see as a mini-BOB) is related to how the mind functions in a crisis. One bag. Grab. Scram. No need to think/decide WHICH bag.
One bag. Always the same bag. Always in the same place. Grab. Scram.
