I bought my GPS unit at the start of last summer, and one day at work I was surfing around on the internet, and found a link to geocaching.com on somebody's website (might have been Robin Lovelock's actually!).
Anyway, went to the site and was incredibly suprised to find 4 sites within 20 miles of my house.
Took a half day, went out and found my first one.
And now, I live on an island which doesn't have any caches on it...
It will have soon, as I'm planning a multi-cache for the island. I'm just hoping someone will come over and search for it......
