That was a pretty kick-ass scene. It appears the reason they stopped was because the cars contained the explosives that took out the rest of the zombies. They went as far as they needed to go to join the others. When the z’s got close enough, the explosives lit off. Nice move. What would I do? Great question. I’m a Walking Dead newbie, so I have some learning to do before I can give a decent answer to that question. Hence, why I joined this community. I recently did a marathon of the first few seasons of TWD and now I’m hooked. I couldn’t resist watching the new season opener though. Now I have to go back and catch up before I move on. I was completely lost in the episode, wondering who many of those people were, but that scene made it worth jumping ahead. I look forward to learning a lot from the community here! Glad I found this resource for zombie apocalypse newbies like myself, as well as seasoned apocalyptic zombie chasers. Awesome!
