I forgot to mention my method of escape:
First, I'd take a backpackers pack and load it with lasting food, water, and a transportable water purifier, along with basic camping equipment (flint, blanket, sleeping bag, etc. Then, I'd sling my shaolin spade and M1 Carbine over my back, and stick my trench spike in a holster on my belt. I'd also have a fishing pole (you'll see why later) I'd get on my dirt bike (along with an extra pack of fuel) and start off.
Take your time, imagine this image. Is there anything more badass?
Then, I'd travel as fast as I could towards the New Jersey shoreline, hopefully recieving little zombie resistance along the way. Once I got there, I'd hop onto my conveniently located large sail boat (complete with large amount of supplies). I'd take my boat out into the sea and sail along the atlantic coast and then into the Gulf of Mexico. From there, I'd travel to the nearest offshore oil platform, climb on, and use the sea as my source of food. Off shore oil platforms have plenty of water and the essentials, so I'd be able to live there comfortably for a long time. If I ever needed to abandon the oil platform for some reason or another I could easily jump back into my sailboat and find a nearby island or just live out of my sailboat, using my fishing rod to catch my food.
Easy as that
