I agree with you, I have a 3 day pack (as well as the wife and kid). I carry 3 days worth of rice, boullion, beans, jerky, some protien bars and a few "goodies". However, all I have to do is get to our pre-determined meeting place. It is 2 hours away via 1/2 interstate and 1/2 dirt road. There is food supplies there as well as shelter, water etc... Our plan is simple, drive if we can, walk if we must, make it either way. We also carry handguns, a shotgun and a hunting rifle. If it has 4 legs and I am hungry... it just became food. I also have one backpacking fishing pole that I could grab if we are headed in a direction that has lakes or streams. Food is only as distant as nature allows.
