So I was going though my truck yesterday, resupplying my SHTF bag and my winter vehicle "snowday" box and got to thinking about food. I used to have a couple day supply of mountain house food shoved under the back bench seat. What about Peanut Butter?? A can of it, unopened is probably good until 2020 and in terms of calories you cant really beat it. Any reason not to just through a jar in my bug out bag, any downside to 3 or 4 days of just PB?
