If you want to go the extra mile for a friend's birthday mix in a little geocaching with their gift. Give your friend a key, a map and a puzzle. When the puzzle is solved, the picture should display a riddle. The answer to the riddle describes the location where the lock, opened by the key, can be found. The birthday boy or girl also uses the map to find the location of the lockbox containing their gift. The adventure will be a unique experience they'll remember for years to come.
