I have 3 Pelican suitcases and one large pelican rifle case in my Liberty Gunsafe. I can open that and be loaded an out of the house in less than a minute with all we need for 72 hours if we are forced to leave due a incident that would make such necessary. We live a mile from a major rail line and all it takes is one chlorine car derailed etc .
I also keep our motorhome in the next town south of us if / in case our small ville gets greensburged by a tornado etc .....
Primary residence is always the best plan if power fails for a few weeks which has happened before. We’re snug as bugs where we are at .
