As my DD said, why don't they armour-up their vehicles ,they could have driven through the 'chain of zombies' blocking the road?
And it really infuriates me when they walk through the forest, crunching and cracking AND chatting at the top of their voices, straight into an ambush. One of them should have gone ahead quietly, checking the route is safe. They marched straight into Negan whilst have a right old chin wag 
Anyway, I think its Carl.
BTW DixieNormas your name always reminds me of a mixture of Daryl and Norman Reedus when I see you over in Chat and AIBU.
