I do much the same as Eugene. Maybe it's not a proper BOB, but I have everything I might need in the same cupboard at home. I can pick and choose very quickly, and can see everything at once so nothing will be forgotten. This is in addition to the smaller pre-packed backpacks etc. that I absolutely know I will need and are ready to go (always in the car etc.). I can sort and repack stuff along the way or when I get "there", depending on how it needs to be carried. So my BOB pack is a bit big and strong so that I can just toss stuff in rather than pack it carefully. Yes, it might take me an extra 5 minutes at most, largely choosing and unsecuring a firearm...
