Heck, dig a trench, put a line of industrial shredders in it with a slurry drain. The noise draws the walkers in, and so forth.
Very good. 
there was a really good zombie series (by ringo) that uses these. very smart, they kill the zombies, release the insects, wait a bit, collect the bones, and viola! able to use the new asset without much fuss.
Splendid ideas, assuming you can lay hands on industrial shredders, slurry drains, generators to run it all, and/or a crapton of kaboomite.
I agree that a deep trench full of punji sticks would be a handy thing to have around my community, but I look at the Alexandrians, and I think, “these ain’t gonna be the people what dig the ditch.”
Using wood to brew methanol is certainly an option… all the way until I wonder how we’re going to cut up the trees. Without chainsaws. Or gasoline. Of course, the Deadiverse has magic gasoline, so all we need to do is gather a buncha chainsaws…
I rather liked the idea of simply igniting logs and then rolling them down into the quarry. Problem is, you’re going to have to do this from multiple angles, unless the walkers are obliging enough to just walk right into your pyre. That was a BIG quarry. Filling it with burning logs would be a bit of an undertaking.
Well, since zombies both burn, and are attracted to fire, the answer is obvious. The fire feeds itself once you start it.
Problem solved.
How did they cut down trees before there were chainsaws and gasoline?
The survivors are going to have to go olde school if they expect to survive for years. Wood creates the heat to make methanol, charcoal, etc. Methanol makes the modified engines run.

Trained beavers.
Yes, the zombies are attracted to fire so that should work from a central location. Rolling more logs as the bunch would serve to smoosh them as well. The biggest problem is that all the smoke would serve as a beacon to other zombies, as well as other humans.
But the biggest benefit to this method is that if it doesn’t work, you can try something else. If Rick’s plan doesn’t work, they are all fucked. Maybe try both ways?
I still think simply shooting them all could work too. There’s got to be plenty of houses with 10-50K rounds of ammo stored. I can’t imagine there being more than 50K zombies there.
You’ve never seen this movie have you? (if you like stupid horror movies with boobies this is a good one.)
I gotta see this.
Is this a woosh? Handsaws and axes, though it’d take a good while.
Exactly my point.
When assembling a permanent settlement after the zombie apocalypse, the first thing you’re going to have to do is zombie proof the place. Trenches are good. And cutting down trees and so forth.
And not a one of our heroes or the Alexandrians look like a ditchdigger or a lumberjack. Wonder if they had any trenchers at that tractor stop?
Why do you have to rain on my parade?
Fine then. Remote controlled quad-copters dropping explosives from the sky, like Amazon delivering electronics.
Amazon ain’t deliverin’ no more. Just find the damn things and a controller.
For that matter, fly them around and use the propellers to chew up zombie brains.
all you would really have to do is set up a row or three of wood chippers at one end of the quarry - and a small trough to move the remnants back into the quarry itself - zombie is attracted to the noise - walks into the chipper - makes more noise - another zombie follows - etc.
We’ve already seen them using heavy trucks and machinery, I’m not sure it’s that much of a stretch for them to lay hands on abandoned industrial equipment. Heck, it might be easier since they don’t have to bother filling out permits.
I have just skimmed, so perhaps someone else has pointed this out, but killing walkers en masse means destroying individual brains en masse, or, failing that, effectively obliterating their limbs so that locomotion is impossible.
Without really big things that go really big boom, which, being the apocalypse, they don’t have, I don’t see how they could accomplish it.
I don’t think Rick’s idea was as bad as all that. Given their mindless forward movement, and that it is so very easily manipulated by sound, I would MUCH rather send them away than let them continue to multiply and hope we can build barriers big enough to hold them back. Because if said barriers ever fail… well, see ya.
An acceptable alternative would be to lead them off a big ass cliff, if one is nearby, or find away to use what big-boom technology they have to blast the quarry deeper, although without being able to temporarily remove the walkers to have access, I can’t see how they could do that, either.
It does seem that the writers have whomever exploiting the fatal flaw in Rick’s plan that could really fuck everybody, and that’s the biggest sound coming from the wrong direction. They should have had loudspeakers blasting sound from the car or something.
It will be very interesting to see if they can re-direct the horde or if it will overrun everything and send them all on the run again. That would kinda suck. Be nice to see the characters create something settled for awhile.
I wonder why they dont use trains to get around?
A big train travelling on tracks would be zombieproof meaning I dont care how many zombies are in front those things can just push on thru. They could use one for colony to colony transportation.
I think the mass quarry/deathpit idea is bad because the zombie poison might be able to enter the underground water supply. Better to leave them on the surface and burn them.
Granted we dont know if there is such a thing.
Much better. See what you can do if you apply yourself?
