The River Aire is 71 miles in length, part of the river is canalised, and is known as the Aire and Calder Navigation. You are looking for a cylindrical container with just the logsheet - please take your own pen. There is a gamecard for another game very near the cache - please do not take this away.
Bring a Pen - There are few rules in the game. But one rule is that you need to sign the logbook. Always pack a pen to make sure you're ready to sign your Geocaching username, the date, and leave a note.
