The only thing more humorous than some of the things people pack in their bug out bags, is the people that don't have one...
SHTF can take many forms and GrayShadows kit should pretty much be a standard for anyone who leaves their home. I have had an emergency kit in every car I have driven for nearly 30-years. When I got my first car at 16, my mother of all people gave me a gym bag with extra clothes, a first aid kit, road flares and jumper cables. It's just smart thinking....
I guess we have different opinions of prepared. I have a few basics in all the cars, and so far in 52 years I've never been caught short, and that includes growing up in MN, going to school in CO, living in the high desert of CA, and most recently NH. There's no way I see--nor have I run across--the need for 50 feet of black 550 cord, 20 feet of fishing line, Small sewing Kit, etc. You can play this game endlessly; "Yeah, man, but what if you were stuck and really
needed quick-don SCUBA gear? Where would you be then?" What about an AFD? Solar stove? At some point, you're buying a larger car to haul your "kit."
The OP question was "SHTF when you're at work." Hurricane Katrina and the Blizzard of 78 (cited above) gave adequate warning of their approach.
Maybe, and I'm going out on a limb here, but
just maybe if Hurricane Katrina was approaching, it might be a good day to call in sick. Natural disaster? I'm sorry, which one would create a SHTF scenario? The Ice Storm of '08? Technically I don't think the S has really HTF if you can drive 45 minutes and get generators/gas/water/food/see a movie. I don't recall social order breaking down during the Blizzard of 78, or the flooding in '06, and everyone escaping and evading to the White Mountains.
I'm not against preparation. My point is I'm terribly confused by someone who thinks they're going to drive
to work through some
Escape from New York post-apocalyptic landscape, or blithely past the sirens announcing the arrival of Katrina II, and packs accordingly so they can "bug out" from work when the S
really HTF. I am willing to admit this is
my shortcoming.
