I had a little tool kit I made up and carried also, but you have to be real carefull loaning it to stranded motorists.

#1, when you get a call and have to leave, they don't understand it when you want to take your tools, bought out of your own pocket, and leave before they are done trying to do whatever it is they are doing, and

#2, California being the home of more attorneys than the rest of the world combined (give or take a few), you've gotta worry about this guy, who doesn't know enough to bring his own tools, using yours to try to fix that can't be fixed, slipping and barking his knuckles, then wanting to sue you and the department for giving him to means to hurt himself...
