A friend of mine just wrote to remind me of a good book. You and the Police is an excellent book by Boston T Party. Pays for itself in just one traffic or other ticket.
There are so many "just one" items around. Fire extinguisher, tourniquet, attorney on retainer. Makes a good subject to discuss. What are some other "just one use" and it's paid for itself items?
Harbor Freight multifunction tool Come-along tool for the truck, to pull out of a ditch Big hammer Air compressor and power nailer First aid kit spare tire for the car bear spray when hiking
Other items?
