I used to keep one...
2 changes of everyday clothes, at least one change of work clothing, some cash, a collapsible fishing pole or two, misc. lures, sleeping bag, keys to the boat in a slip, and a few bottles of whatever. I used it numerous times - every time the ex-wife would go on the warpath. The bug-out bag made the difference between just getting kicked out of the house, and suddenly embarking on an impromptu outdoor adventure... AKA "Free "Hall-pass" LOL
My ex was the only person on the planet scary enough to kick me about of the house. Now that she 'aint around, I'm not leaving the house for nothing... I'll stand & fight. No bug-out bag needed.
...unless I see her and her attorney headed my way. LOL
Very well said!!!!!
