Do you think they will all make it?

Or do you think someone will either tap out before the end, or have to be medically evacuated?
I am betting on Rick tapping out.

Also, I think that RR handcar they found was planted.
I hope they know the train schedule, it's probably only once a week or something in that remote area but still, they moved the car to the main track so if a train comes they are royally screwed.
