I would then refer you to the episode of the Governor's burning pit........
As for leading "them", who are you refering to? The few thousand hoarde in the nearby city? Good luck with that..........
In every city, there are places where you could rig up a trapdoor setup, like off a bridge or overpass, where you could bait zombies to "walk the plank" off a ledge where they would be killed, or their legs broken by the fall. Would a zombie figure out that every other zombie is falling to their doom? Or would they just keep trying for the bait and go off the cliff like herd of lemmings?
