Lone wolf by far. Even if you have your family with you, what happens if moms gets bitten? We saw what happened in Night of the Living Dead, 28 Days Later, and Shaun of the Dead. You definitely will hesitate in killing your zombie relations, and assuming that hesitation doesnt kill you, you will have an emotional breakdown. Best to live by your own wiles in a remote location with an enclosed area for livestock.
Also as to food...consider this. Chickens will lay an egg per day, and cows will continue to produce milk for a long time. Agriculture will @#!* you in that a frost will leave you hungry, and canned food only lasts so long. Clearly you need to prepare a walled grazing area.
