Very true for any disaster is the 72 hours plan. Even up here in snowstorm country, kids and adults are reminded what they should have on hand or in the car.
Some sadly, for whatever reason...think they can beat the odds on their own.
I was a route 128 commuter during the blizzards of the late 1970's. I was fortunate but some of my coworkers were stranded on the highway. Everyone put together an emergency kit for their car trunk after that. I'll bet not 1 in 50 does that now.
