Wow...Never new there was a science behind "SANDBAGS"

These are much more intuitive tutorials then what my company has me watch so that I become certified in various aspects of Human Resources/Payroll.
I have always said" If he cant or doesn't want to do the job, Sandbag him" Now I will say it with authority.

I never really understood where folks would get the necessary sand to fill said sand bags in an emergency situation / shtf....Busting the stored bags out to build a safety wall would be awesome, but no available fill would be the reality for the majority.

In Korea, during the monsoon seasons they would send us to low lying Camp Red Cloud and give us sandbags. Then we put them on top of each other. That way there would only be 1 foot of water inside the sandbag perimeter instead of the 2 feet outside.
Didn't realize there was anything more to it than that.

I prefer to live where, if and when there's a flood issue, there won't be anyone left to give me problems
