15 minutes really isn't a bad time at all there's really not that much involved it's just a matter knowing what to do and how to do it. I'm begaining we may all ready be there too. People to often forget how unpredictable life can be.
That's not a bad time to bug out. I can only imagine what's involved, especially with the risk of having things flying around inside the trailer.
It's interesting, because in my 56 years I never thought I'd be seriously contemplating such things. I worked with a fellow back in the mid 80's that was a survivalist; he always thought the Russians were going to drop in like in "Red Dawn." I never did, but humored him. Something made me think that the US was going to implode one day and end up like the Roman Empire. I am starting to think we may be there.
