Hospital ...

Why are these people in a hospital that has "infected", blood-thirsty monsters around every other corner ??? Plus, one couple says "we've been here 3 weeks" ... WHAT ??? Also, the farther they go (looking for this mysterious, super-special "door"), the more "infected" monsters and chewed up bodies they find !!! Get the "flock" outta Dodge, people !!! If U keep seeing MORE blood, MORE monsters, and MORE chewed up bodies, ... U must be going THE WRONG WAY !!!
