I have some prep done at my home, more than adequate gear but really need to lose a few pounds and discipline my kids.
In terms of gear, are we talking about the B.O.B. (bug out bag or 72 hour bag) or the I.N.C.H. (I'm not coming home) bag?
You definitely want the following:
-Multiple ways of starting a fire
(cotton balls in Vaseline, flints, matches, etc)
-Multiple blades including at least one "chopper" like a hatchet or kukri
-Water containment and purification
-Fish hooks
-Sewing kit
-Mess kit w/ can opener
-Medical supplies including gauze, asprin, benadryl, disinfectant and epipen/antibiotics/quikclot as funds allow
-Crowbar
-At least 100ft of 550 paracord
-Tarp
-Firearm you know how to use w/ ammo (keeping weight in mind)
-Multiple pairs of wool socks (cotton kills)
-Calorie dense food (fish in oil, dried fruit and peanut butter are all great)
-Compass and various maps (especially railroad and topo)
-Dog whistle
Keep these in mind and you'll have a pretty good base. The paradox is that you want multiuse items to economize weight and space but also want to have redundancy in case something gets lost/broken/bartered.
The usual things but one rarely mentioned is a book on your local flora. Youre gonna be eating a lotta plants and a lot of em are poisonous. No I dont prep, first place Id scout is the local pharmacy because meds/pills will be valuable currency. Secondly sports shops. Most likely Id just die or get kilt.
Ding ding ding ding ding!
