The best way to test a BOB is, of course, to use it. Since you presumably have a destination, follow your projected path and become familiar with it. Many internet BOBs are clearly proposed by inexperienced folks who are indulging their fantasies. They need to get out more often.

To achieve admission to the inner circle of BOBdom, join a wilderness SAR group and keep a pack ready to go at all times. Experience will hone your gear selection, which will be tweaked in accordance with the seasons and the weather.

You will also have the experience (and gratification) of helping others, something that will come in handy during an emergency.
