Okay - I've figured it out. Once we get going (April 29) I'll send out our location once or twice a day using the Spot satellite device. If you're interested in finding out where we are, all you have to do is open a web page, which will display a map with a breadcrumb trail of all our locations up to that point.
The web page address: tinyurl.com/seaducktress
Pretty cool, eh?
