The worst feeling is when you need x and don't have it. That's why I started carrying a BOB long before I knew that they had a name. And having them doesn't mean that you must use them, but it certainly expands your options.
You can survive an attack without weapons, tactics and strategies, but you'll fare better with them ;-)
Well I searched the net to find out what a BOB was. The closest I could find was Battery Operated Boyfriend.
So you pull out the BOB and everybody falls on the floor laughing? Do you think that will work?
