Maybe I should start a new thread, but I think the following ideas apply to the present thread :

For a Bug-Out situation :
Some forumites have explained they have pre-positioned BOB at friends'or parents' houses.
What if you don't have friends along your probable/preferred escape route ??
How about using this kind of storage to help in a Bug Out situation. (or any other self-storage provider... I just found this one as an example)
One or more small room(s) rent along a pre-planned escape route, just out of the supposed dangerous area, may help you to rapidly escape the big city with a minimum kit and replenish easily on your way to your final BO location, whatever it is. Some kind of urban geocaching ...

And how about leaving a (prepared with water/food/gaz...) vehicle (old/cheap/...) someplace out of town (friends/rented garage...), so you could escape more easily on bicycle (with a light kit), without being detained by the congested streets of your town.
Some other poster said long travel on bike is difficult for untrained folk. But if you only have one or two days of travel on your bike... and then get abord your car ...??

Or this idea could apply to folks living in a flat, without possibilty to keep motorcycles with trailers full of food/water/etc... ready to get out of Dodge. For parents with two young kids : two simple bikes are easier to store around the flat; little kids can be transported on rear seat of each bike. No obvious goods tempting would-be thiefs on your way out of town.
Arrived a your self-storage, get your motorbikes/trailers/car and more substantial kits and you're good to go further, faster..


P.S. : I don't remember seeing this idea developped on the Forum ... but maybe it has already been suggested....
