I can answer questions about Geocaching rules, customs, and guidelines. I can also provide advice about what types of features you should look for when buying a GPSr for Geocaching. I also provide assistance in solving puzzle-related Geocaches (or at least my best attempt - no guarantees).
I have been an active Geocacher for over 4 years and have over 2000 finds and 100 hides.
I use a Garmin GPSMAP 76CS.
