I was looking for a GPS unit for an odd reason. My other hobby is photography, and since we have moved to MD, there are some beautiful, OLD, places to photograph. Well, I always see these places when we are en route somewhere and I don't have my camera. So I thought if I could just mark the coordinates, I could return with camera equipment and good lighting and do some shoots. WELL, while googling, I checked out Garmin, and its site had the geocaching section. The rest is history.
