McDonalds hiding amongst the plastic balls ( how about the roof? )

I really cannot think of a more stupid thing for Alicia to do than to get spooked and climb up and into that kiddies play area with the many balls.

Of course, there is a "zombie" in there to drive the plot, but ask yourself how did a dying girl get into that spot?

In any case there is no way to get out or to even defend yourself stuck in a transparent place like that ... it was truly stupid.

It seems to me that a good place to go in a situation like that is to get on the roof. No zombie can climb up on the roof, and after a while you are not visible so the zombies will walk away and you can eventually get down.
