Geocaching revisited

Hi all,
I did a search and found that this topic has not been addressed for a few years...like 4(?)
While surfing the Web I got interested in this hobby and just bought a GPS handheld unit (Garmin Rtrek HC on Ebay) and thought I would start a thread about Geocaching while camping. I joined Geocaching.com. It seems like a great way to have some fun while out in our TrailManors.
I noticed that Bill, one of our Moderators among others, was or is involved in this sport and thought there could be some interesting insight and feedback to this topic.
Anyone care to leave feedback? Good? Bad? Tips? GPS units? Pictures? Experiences?
Thanks,
Jerry
