This is a different way of thinking and I can’t say it’s perfect. Most Preppers would say to pack each item as a separate bag as if you are going out alone. Frankly, I’m not going out alone. If my family can’t bug-out with me, I’m not likely to bug-out. I’m not leaving anyone behind.
I’ve been checking out a few bags I like. Remember that high visibility bags are not good. I found a few bags here. Good bags, military grade and some of them are pretty cheap. Fifty bucks for a quality bag is a great deal. If you are thinking of specially-packed bags, how about one of these? Holy cow, an ER in a back pack? Wow!
Get those bags ready, my friends. Start simply and build them up over time.
