Anything is possible.Raveon sells MURS transmitters made for vehicles that can send, among other things, GPS tracking data to keep track of fleet vehicles. I imagine it would sound a lot like the dog trackers if used for just that purpose, but stronger.
Could a business in the area have these on their fleet vehicles?
