Either way, if you’re so inclined, you can pick up the teeny-weeny
TrackStick Pro, which comes in a variety of colors for volume orders, depending on who you are (red for emergency, olive green for government, and boring gray for commercial interests), though price and availability have not yet been announced—you’ll have to contact the company and explain how your use will be far different from stalking. This little buddy will require power though, by use of a cigarette lighter, so pretty much don’t expect to track anybody who’s unaware of it, unless you get tricky and tell them that it’s an iPod power adapter. Clever you.
