In case of mutated animals/humans, I could get weapons from my dad.. He has a M1911, a 12 gauge, a couple semi/bolt rifles, a half a dozen BB guns and for some reason I have 10 pounds of AK-47 ammunition in my garage. Oh, and I could steal the two gas masks one of my friends has! I also have relatives in Texas if that helps in any way.
EDIT: Anyone consider taking over Florida for NASA? We could use the ships to get off the planet in the worst-case scenario
