I'd prefer to stay in. The majority of my supplies are at home, I know the layout of surrounding area, I know where I can get supplies easily, and I have a better plan of how to defend it should the need arise. I think bugging out should be the option when your primary location (home) is compromised to the point where an unfamiliar place with limited resources is the best option.
Roger that !!
Don't pick a fight with an old man. If he is too old to Fight, he'll just kill you.
