Hmmm... There's many ways to escape from this city. Your best bet is to actually hot-wire a car and break into a gun store (if you're not of age and experience to buy guns yet, like me). Grab a rifle, shotgun, hand guns, katanas, machetes, anything you deem fit to shoot/slice up those fuckers (I reccomend the shop on 944 Bonifant Street in Silver Spring). Then, your best bet is to grab as many supplies (to last) as you can and travel to the Chesapeake Bay Marina (located on 3501 Red Rose Farm Road, Middle River, MD, 21220). Break into a house boat (make sure you have gas) and sail out to the middle of the bay. Zombies can NOT swim, so you'll be safe there. When it's time to restock, go back to the nearest city (making sure to grab as many weapons as you can) to reload and restock. In time, you may sail out to any isolated islands to try to find survivors. Alaska, the Carribeans, and other islands are recommended, but I suggest staying out of any MAJOR cities (Las Vegas, New York, they're all heavily populated).
