A question
A brief scan didn't show that anyone else had come up with this question. It's a long shot, but I wonder.
I am by no means sh!tpicking here...just saying what I would have attempted to do in this situation.
The concrete barrier that killed the first thing, grabboid, whatever...that looked like a channel...obviously the barrier killed one at full speed, and they can't penetrate it...couldn't they have followed that somewhere to safety or to alert authorities? Maybe it didn't lead all the way where they would wanted it to or something...just never heard them address it in the movie.
