Lets see, Im gonna try to make a list using things I actually have...
Dad's Hunting shotgun (no ammo)
3 shovels in my garage
Food, water
Walkie talkies, and that empty lined journal thing i've never used.
Assuming my parents arent their to interfeer, id gather my friends with similar equipment and set out for weapons and supplies.
So all in all,
4 people group
2 small arms low ammo
Several bludgeing weapons
and food for a week or two.
So we might last a little while :-/ We all know not to over react/what to do and what not to do during one..
