Alternate transportation?
I know it's just a movie and Hollywood can do what it wants. Had to get that out of the way. This movie had me wondering one thing. Why wasn't anybody riding bikes or using horses, or other modes of transport, instead of just walking?
While I know, after the scene where the girl was shot, that there were snipers along the road, a bike would have people moving faster, or even a skateboard. Did the EMP and the avian flu also kill off the horses & mules, and other forms of transport not affected by this? I'm sure a few horses survived(immunity to the flu, like humans). This movie had me wondering why people were walking everywhere.
Also with the flooding, not every house or farm was damaged.
