ITT - People who would die.
1.) Deagles are impractical, the recoil would break the wrist of an inexperienced shooter.
2.) .50 Cal snipers are not easy to find, srsly, they don't sell them at your local gun stores.
3.) Crowbars, Machetes, etc < Guns, things that go boom, etc - if you have a firearm, forget a melee weapon, it's just going to slow you down.
4.) You can not effectively move around while carrying a literal forgetton of supplies.
5.) @Spas-12 - Another impractical weapon, I do not know of a single decent military/police force that puts this weapon to use because, it's that bad, either you wouldn't find one or wouldn't want to use one.
6.) @M4/AR15/M16/Other Armalite weapons/Weapons that fire 5.56 rounds - Assuming zombies do not need organs to live or whatever, your silly 5.56x45mm shooting guns will simply tickle the zombies, get something with stopping power or get out.
7.) Listing valve characters is handicapped.
My list/Plan:
Food
Backpack
Plate Carrier
Plates for the plate carrier
Water
Cellphone
Flare
I would head to the nearby military base and wait.
