Actually a good suggestion. If the good guys dressed
as walkers they would be no more or less attractive
to walkers as Beta. Imitating walkers was a ploy used
by Alexandrians in the episode in which Carl had his
eye shot out. It is not new to TWD.
One strategy to try would be to trap as much wildlife
as possible. When the Whisperers are leading the
Walkers to attack they will be distracted by deer tied
to trees in strategic locations leaving the
Whisperers vulnerable to a mass sniper attack.
Yes, I remember the episode with Carl and they drenched themselves with Walkers blood and skin.
That is great idea about the wildlife ploy.
They also should dig a huge pits on the path of the walkers to the fort before they get there. Drindle the numbers down to have to kill.
