I'd get guns from the local gun guy that just got caught with hundreds of automatic guns in his basement because he was "preparing for the apocalypse". Take those and his ammo, and since zombies cant swim, live on a local dock (fishing community) and hang out on someones boat with the engine off and anchored in the middle of the bay. Also, the supermarket is right across the street, so I would go there in the day. Either that or I would take a car and go to Maine and live in my cabin on my awesome boat. To anyone with plans of flying, airplanes use lots of gas and if you cant land (eg ton of zombies) then you are gonna crash
