I’ve been prepping for a long time!
First of all. I was a kid during WWII and I learned then about scarcity and rationing. Later on, my parents always had a well stocked pantry we rarely did any last minute shopping for anything.
In college, I began hiking and technical climbing and began to equip myself for potential emergencies. I also had my first search and rescue experience, very educational.
I eventually made a career in the National Park Service, frequently in isolated spots (Wupatki National Monument) and continued my volunteer SAR work which soon became rather frequent.
I soon learned that I needed a bag, packed and ready to go with basic items, and with other things organized within quick reach. The items within this bag needed to be changed with the season and location of the operation,
Later in my career I came to Channel Islands National Park, a fabulous place with many isolated spots. Relief was not always on time and packing extra food was routine..
Living now in SoCal, I routinely prep for wildfires and earthquakes. I still maintain a bugout bag which was handy when wee had t leave at 2 AM when a big fire came through. I am prepared to remain at home if we suffer a big EQ, which is likely to be a good initial strategy.
