How about changing "bug out" to evacuate?
Why don't you tell our members who live on the Gulf Coast or those of us who live along the Front Range how the concept of bugging out is just fantasy?
Where do you go? ANYWHERE but a government run evacuation center.
I am from the Gulf Coast, I was in Camille. We did leave for Camille, there was nothing left of my grandparents summer home along the coast where we had been staying. Most of the time we shelter in place during hurricanes, the modern day Weather Channel/climate change hyping did not exist. The right decisions are made before, not during, as in picking a home site that can generally weather a storm surge. Being from the Louisiana Gulf Coast, whenever I look at property, it is in my DNA to look for high(est) ground regardless.
If you live in a place where you think you might need to evacuate due to a natural event, you should have an away kit already prepared and a vehicle capable of making it's own way, not the Priuses I saw on the news programs in California. And money and fuel to get you far enough that you can get a hotel room or safe relative. Again, decisions made before, not 20 minutes during.
Where I live now, short of a biological attack or nuclear attack, the only thing would be a tornado for which we have a hardened storm area in our basement. I do keep a rescue kit (not a bug out kit) ready to go, for real! It is for rescuing my parents/relatives still in Louisiana and I did go down for Katrina. I keep four 6 gallon cans of gasoline at all times, I have a 12 foot hard floor inflatable boat and motor, food, water and a selected weapon and sufficient ammunition for it. I also have rope/line, tow straps and off road jack, come along, chainsaw with fuel, small generator, two spare tires (go in the roof rack) which all fits into and on my lifted overland prepared Tacoma 4WD. This all stays kitted in the back of my barn.
So, yes, deciding in short notice you need to bug out and with no plan or preparation and then suddenly worried about ammunition, that is a fantasy, ammunition would be my last worry if so unprepared.
Oh, Katrina, I was rolling, unable to reach my brother, sister or parents. As I crossed into Louisiana at Shreveport my brother called and said all was well and I was not needed. So I turned around and went home. Went back a little later to clear trees for my my brother and sister at their home places which both did fine (you know, high ground). He has a back up whole house home generator and so does my sister (now). It was a mess down there.
