I just recieved an email from Magellan about their new summer game. Last summer they hid caches with nice prizes and posted hints every few days. Most of their caches were near major cities, with Chicago being the closest. Maybe they will place one in Wisconsin this year. Check out the link below, you need to register, but don’t need a Magellan reciever to play: http://www.magellangps.com/en/gpsAdventures/geocaching/
