Your wife has taught her well hasn't she Dan? To track the girl you can use a gps system. I would hide it in the trunk underneath the spare disguised as a tool, or something that belongs in the car's trunk. Tacking it underneath would lend it to loss. Too easy to fall off.It sounds like you are having trouble with a rebellious teenager, I do hope it works out for the both of you. Because when the father has to track his daughter to that extent, then the child is in real trouble when she hits adulthood.I hope things will be resolved between father and daughter, I hope all goes well in the end. Best wishes to you.
