My personal Bob is my camping gear packed and ready to go minus food water and clothing. I have a duffel bag of clothing and a "messenger" style bag with more urban based tools that i would grab along with with it. I think making a BOB and never touching it till you figure it needs to be updated is a wrong approach. For most people in areas that are not often hit by natural disasters its a waste of money to double up on the same stuff just because thats what everyone else does. Camping gear and bugout gear is little to nill in difference. The big difference is the added Tools such as hammers and so on so forth and extra items for repairs such as duct tape and such.
