Weapons...

Why are they so dumb to ditch all the weapons, they killed a guy with a gin, they ditched the axe and didn't take the gun...

They run to a military guy, they get rid of him, they don't take his big-ass gun.

Fat guy runs to save his friend from butteater, does not take the spike which he killed previous zombie with.

And I thought scouts would know a little bit about survival...

The Hardware store:
Before they go there, they say hthey have 2 hours before bombs go off.
They build weapons there, so at least 1 hour gone...
