The dead are trouble and they create problems everywhere. If they'd just gone away and left the living to survive in the post-apocalyptic world, everyone would have been fine. People would have found a way to cope with things even if some people would have died.
It's their presence that is causing so much trouble on both sides of the border. Tijuana's people, I don't know how they survive in that city. And how they manage to stay away from the zombies so well that they've time to set up a trap for the Water Queen.
Daniel was right, when he pointed the wall and said: "One third day they'll hang us from there." It is a never ending cycle. A coil of a serpent that never ends. Even with help of Ranch's armoury the dam is going to be in trouble if they don't find people to protect it from the living and the dead.
If they go in five days to make trade at the stadium, more people are going to know about the dam and it's valuable resources. So they're only in luck that the media isn't there making it known to everyone. Maybe ultimately, when they've walled Tijuana, the dam will act as major beacon for the camps that are spread around the Mexican desert. After all the old wisdom is that you travel in desert between the oasis.
Strand was clever for figuring out the car locator trap for the dead. With that system they could section part of the Road to Tijuana and make it as a border zone if nationalism ever rears its ugly head. In theory it could work with a large horde as well, but setting it up is going to a humongous task. So I believe that sooner or later someone will learn how to heard them as if the dead were cattle.
Dangerous cattle.
I wonder if Madison ever stop to think about the past, because she has come long away from the place where she was school counsellor. That thing is a distant memory. If she'd done, maybe she would understand that Walker is the enemy. He left her in trouble and swore to hurt the Ranchers without even knowing what is happening there at the top of the mountain.
What did you thought about it?
