Here is one for geocaching cruciverbalists. I have tried to compile this crossword as relevant to Geocaching as possible without being too contrived. Of the 26 clues and answers, over 20 of them are directly connected to a Geocaching theme. Some of the connections are quite tenuous, so use your imagination. Visitors without in-depth knowledge of 1 across will find it more difficult than locals. I encourage all to have a go.
Once you have completed this crossword, the highlighted letters should be rearranged to form a word. This word should be entered into the certitude link below (in CAPITALS). If correct, co-ordinates will then be given.
Good luck.
