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. Jim Sean H.
