I've written several hubs on this, though as fictional works.
First, stay home and join up with neighbors to fortify and keep watch.
Second, if you must, retreat to a secure nearby location. Walmart regional distribution center or some other industrial building with valuable supplies and few entryways compared to a grocery store.
Going to a rural retreat is risky because you're in the open and vulnerable to both zombies and human predators on the move AND vulnerable as a poor refugee on arrival.
