Your initial gear list includes Sangean DT-180 AM/FM radio. Since information is king during emergency, and timely travel-route info is particularly crucial for you (identifying open bridges), would you be better served by substituting a small handheld multi-band receiver (providing access to more than just AM/FM ... police, fire, emergency responders).

Others living in your area can better comment on real-situation benefit, or does it merely sound good 'on paper?'
