I love it! And how could I go abroad and NOT take the opportunity to do some foreign caching? I use a handheld Garmin unit called the GPSMap 62s. I actually have another unit, too (Garmin GPSMap 60CSx) but I think I'm just bringing the 62s. There is a 2-minute video at www.geocaching.com that explains the whole game.
