I'd stay. Hell with the "I don't wanna die here" shit. Build a bridge or tunnel or something to the gun store, clean out the zombies in the basement, get the generator running, and there's no reason to leave.

Precisely.

Besides, more people died just by leaving than would've by staying. Way to go, Ving Rhames

I would've stayed in the mall until every supply was used.

I'm assuming that there were more than just the two propane tanks that appeared in the movie so I would've thrown them off of the top of the mall taking out all the zombies in the immediate area.

Then I would've proceeded as fast as humanly possible to the gun store and loaded up on as much ammo I could then try to find help.

In Shaun of the Dead and the Walking Dead, characters in both stories where able to go out amoungst the zombies by acting/smelling/looking like the zombies.

i would hot wire a truck and do a ehll lot of zombie hit and runs on the way to some place far far away

I haven't seen the walking dead, but in SOTD, it didnt exactly "work", you saw zombies turn around almost as soon as they passed...they were slow to react, but they knew.
