Now to D.C.. What would be the fastest safe way to go? Duh! They're at a train station. Load up a cart with all the supplies and guns.
But can a herd of walkers on the the tracks derail a train? They stopped a POS car. And another character death scene: a track switch has to be done manually,
someone has to jump off to save the group.
You haven't played
The Walking Dead: The Game by Telltale Games, have you? In one of the episodes, the characters find a train that is still functional, found the start up sequence list and got the sucker rolling in order to get to Savannah. The perk was that it was practically unstoppable when it came to hordes of zombies. The downsides? 1. they had to stop for anything that couldn't be plowed through (in the game, there was a gas tanker truck that was on an overpass, and it's trailer was hanging off right over the railroad and in the path of the train, which mean they couldn't just plow through it). 2. The fact that there are no other sounds in the world, and the fact the train rolling down the tracks attracted every Walker to the train tracks all the way to Savannah. Even though the group got a few hours worth of a lead on the horde that had followed the track, hours later, they showed up at Savannah because they followed the track until there was a mega-herd throughout the streets (you know that Mega-Herd that they encountered on the run to the college in the first half of the season? Times it by three, and you get a bit of an idea on how big the horde was in Savannah).
My point is this: no vehicle is ever going to be good enough. A train would have to stop for any possible obstruction that could cause severe damage to itself, and from mid-Georgia to Virginia would end up creating a mega horde that at minimum would be five times the size we've seen Daryl, Michonne, Bob and Tyreese encountered, if not more than five times that.
And I heard rumors of a spin-off series. How about this scene: Manhatten Island? The bridges are barracaded. Building to build sweeps of walkers.
Random out breaks of walkers within. Central Park becomes farm land. And also trying to keep the people humanized. Trying to keep justice.
So many possibilities. Just some ideas
Manhatten Island was used in
I Am Legend, so though a good idea, people would just draw too many parallels between the works. If anything, I'd guess for a spin-off, we could see something happening somewhere in the central to west coast of the U.S. I mean, we know the zombie plague is world-wide, so there's more to this story than just Georgia.
