This video brought the question up and I got to thinking
Personally I have two. I have a level 2.5 assault pack/ get home bag (old bag shown as the new one is pending a post) and a bug out bag. We also have some stuff in the family hauler and there is a BOB for Wifey. I don’t really plan on adding any more kits unless they are for caches. A cache like Meisters‘Minute Man Cache with a rifle, pistol and BOB would be awesome.
