all the gas in the world is all the gas in the world
Yes and no ... They've been scavenging gas from abandoned cars and filling stations. For their limited use, there should be a ready supply given there's not much competition for the resource.
But the real SHTF fuel is biodiesel, diesel engines will run on just about any fuel source. It's a relatively simple process to make biodiesel, and unless you live in the Great White North, ay! you won't have to worry about it gelling up.
Maybe if they start growing enough food to keep everyone fed and distill moonshine on the side
Always a good plan for so many reasons. Fuel, antiseptic, sterilizer, anesthetic, orgy ... Whatever. There's tons of good uses for pure grain alcohol. :cheers
But I don't think that simply propping poles up against the frame of the fence would be enough, as shown in the last episode. I'd, personally, feel much better with a solid wall or if the fence were reinforce with more than just a few wooden braces here and there.
The way the fence failed was unrealistic. A chain-link or "cyclone" fence is more likely to be pushed over. You can drive a car into this type of fencing and it won't fail in the way they showed.
However, if you tied the two outer fences together with lengths of heavy gauge wire then filled the void with a mix of rock and earth you'd have a very stable and strong wall. They could even walk along the parapet tower to tower. Yes, it would be a lot of work. If they started shortly after Woodbury when they had maximum people and acquired a backhoe-loader.
As far as that mega-horde we saw previously, one of those 2.5ton army trucks Woodbury had could push through with little issue, but then TWD isn't sponsored by the US Army which is why they keep driving Hyundais, Kias, and other small cars.
