Keeping your passport around in a BOB is kind of like keeping your social security card in your wallet. You need to get them out for certain activities, but it probably isn't a good idea to store them in a semi-secured where it can be stolen. I like the idea of keeping those documents in a safe in the house and grabbing them as I go out the door if necessry. I used to keep that documentation in a small fire safe that was easy to grab and go. In a gentler time I used to keep the key in the safe so a burgler would see it had no cash or jewels and leave it alone. Now the identitiy theft would be much more lucrative than cash! Now those documents are in a much more hardened location.
