Thanks for the replys...
We plan to combine GeoCaching with our metal detecting whenever possible. There seems to be a lot of caches in our area (the Finger Lakes).
Our first choice for a username was "Cache22", but that was taken, it took us 2 days to come up with "Cache Quest" and got excited when it was available, couldn't believe it either...
We've already read everything on the site and most of the forums so we might try finding our first cache tomorrow... (a test to see if we can use this GPS)
