I live in a rural area, near the highway but it's still over 3 miles from my decelopment to it. So plenty of cars to siphon gas from That aren't too far away, and could get materials like lumber from the local home depot/lowes mear the onset.
Between everyone in my neighborhood alone we have about 200 guns and tens of thousands of ammo rounds. We also live fairly near the water and our neighbors have a boat (as well as fishing rods, nets, and scooba gear so we could easily fish). All houses in my area are made of concrete and we have storm shutters. Zombies aren't getting in if it comes to that. :P
We're also always well stocked with canned food and own a generator. We also all own wells for clean fresh water that we won't even need to boil to make sure it's clean. (i live in florida so the ground is all sand and acts as a natural filter)
So I think I'd have a really good chance. :P
