hso - wake up!
For Me the most likely Serious Situation I personally face is:
Older returning student attending college across the river.
Since I am familar with the limited routes to get back and forth over that river and HAVE been in Serious Situations due to Ice Storms, Snow, or Tornados...
I have had to stay put, because the LEO agencies said nobody needed to be out to cross the routes or only emergency personal allowed to be on them bridges.
I have had to turn around and head back to where I started from - and have a plan and place to stay.
I have spent 3.5 hours stuck on that bridge when a really bad wreck, coupled with a Tornado , and sleet - made pretzles out of 18 wheelers and other vehicles. Took me me 3 hours to make 500 yds to an exit. Seems a wreck behind me prevented me / others from going back.
It was 18* F with a wind chill of something really cold on that bridge. Army Blanket, water, and cans of tunafish and vienna sausage...etc., were the better things of my "payload".
Folks thought I was nuts for having a dozen cans of vienna sausage in my vehicle in a ice chest...there was a Couple from out of town with 2 kids that thought I had hung the moon giving fussy , scared, kids vienna sausage.
We had a Doctor, a nurse, a mechanic and other folks keeping tabs and working like a team up there.
Gas can with means to siphon gas handy, engines were shut off, and then back on for a bit - still needed to idle to keep folks warm, especially the elderly and kids. Nobody ran out of gas - we made sure of that.
Doctor, a nurse, mechanic and myself had extra space blankets, amazing how much warmth these things provide inside a vehicle breaking the wind...yep, just those little bitty foil looking ones....
Umm , yeah, I was CCW-ing, not the tool(s) I needed that night, nor has it been for other Serious Situations.
