I've seen some inflatable immobilizers, thoughts from the EMT's?

And yes, I'm over-prepared, I just read an article that the Hayward fault (which I reside on top of) has a big shake about every 140 years, and guess what?, the anniversary was last week, so I have 140 gallons of stored water (one for each year or just a weird coincidence), about 30 of gasoline, and 30 days of freeze dried/MRE/canned food. And the stuff to cook and serve it, I am a bug in proponent since in California I would run out of fuel before getting anywhere significantly out of the fray....

On top of piles of first aid stuff, seeds, reference materials, tools, varmint weapons and ammo (for eating, not defending), and a small motorhome with generator (if safety becomes too cumbersome and bug out is the alternative left).

My wife thinks I'm losing my Prepared with restraint status, yukyuk.
