Interesting post for this forum. I spent 4 years as a Navy survival instructor and I would rate myself highly profficient in wilderness/primative survival. Wandering into the woods for an accomplished outdoorsmen would be very hard. Doing so with a few extra mouths to feed makes it a very dangerous idea.
I also believe this new trend in survival and end of the world stuff is mostly pretty far fetched. Time and time again mother nature demonstrates she is the most consistent threat to a persons day to day life.
Either way- if it is a minor weather event, or a total collapse of the modern world I am buckling down at my place, with my family until things blow over or I am forced out into another position.
The primary concern I have is ample water for my family- of which I believe I have enough for 60 moderately comfortable days without ever opening the front door. Water is cheap and fairly easy to store and preserve. I do have a few months worth of Wise and Mountain House foods. Only because feeding 4 off the land is an impossible challenge if unprepared.
