-Volcano stove with a bag of rice inside of it (figure its dry goods and will last forever), rice is in its own zip lock and so is the volcano
-2 cans of Chunkys soup
-2 MREs
-Cliff bars, Shot blocks, crap like that
-Matches, etc
-2 flashlights
-A blanket
-Couple of water bottles, many are the collapsible kind
-Those little foot warmer thingies
-Deck of cards and a deck of cards for some other game that isn't American...but I figure if I'm stuck somewhere, I'll have plenty of time to figure it out
On top of that, people over the years have bought me "emergency kits", like its in a bag or a bottle or something like that. I've thrown those in there too. Not really needed but, eh.
Except for the food, volcano stove and the survival kits (but those were gifts), everything else was giveaways or freebies from somewhere. So not a lot of money in the entire thing. All of it is in an old north Face Backpack. So pretty cheap investment. Easy to throw in the back if needed.
The goal of the bag is more of a "get home bag" than a bug out. So either stay in place, or try to make the hike home. My office is 25 miles from my house and getting stuck on the road is a real possibility. Its happened. So either be prepared to camp out, walk out, or try to make it to the nearest train station and go back that way.
