Ghille suit, suppressed .22 and a box of Little Debbies in case I get hungry before someone comes by?
My match backpack is grab and go for pretty much full on battle rattle, just have to switch match ammo for defense ammo. But water, food and shelter might be the most important things to have. I think it depends on where you live, who is in your household. While my dog is a great asset living in suburbia, she would likely be a liability on the road. I think modular is best and see what happens when you have to. Part of my plan is to maybe wait out the first panic while making it look like we are gone.
