Me too.  What about using the satellite system that is used to monitor the path of
migrating Whooper Swans between Scotland, Ireland, and Iceland, in conjunction with
one of the tiny transmitters the swans carry on their backs.  Power requirements are
negligible, there is a location update several times a day, and accuracy is fair,
usually within 5-10 miles.
