Betty, have you thought about getting "The Spot" satellite do-hicky?? Looks like a little fob with a few buttons. It has an "OK" button that you can press that will send a message via satellite to whomever that you are OK. There's another button that summons help. Usually have GPS coordinates included with the message. Higher-priced versions and/or competing brands can actually let you send an email/text to someone via satellite. Kayakers use them when going on long trips, especially in saltwater. Might save you a couple days waiting for someone to drive by to give you a jump....
