It sounds like a prohibitively expensive endeavor to me. If you can stash stuff in your vehicle, that sounds like the thing to do. If you know you're going to a friend's - put the main BOB in the car/truck. If you know you're going someplace where you have not already stashed one - same thing. After all - what happens if you're enroute? This is if you drive, of course. If no, maybe you could EDC a BOBlite? Something that will get you back home or to your dad's house where you have already put one. Having half a dozen BOBs just seems really expensive - money that could be used for other preperations. If you're asking a bunch of your friends to keep a spare BOB for you - the cats already out of the bag (so to speak) so the conflict is not so much of a conflict - it's a done deal.
