Additional comment: I just purchased a bicycle built for two which brings my "stable" up to 4 cross-country bicycles with 5 seats (and 1 trick bicycle).

If they couldn't be ridden to get out of a bad area then they can be loaded down with supplies to take with me/my family.

I will be getting panniers, saddlebags, seat bags, and handlebar bags after the first of the year so that they can be secondary stage vehicles for people and cargo, efficiently.

I am seriously considering a bike trailer to carry my DD1 (who is handicapped). She could ride in a "feeder seat" mounted into the trailer, facing backward and there would be room for a substantial amount of her personal medical maintenance items, as well. At the present time if such a need arose, I would have to quickly modify a shower chair to mount onto the frame in place of a bike seat.
