This is a two part cache with the final log book less than 200M from the listed coordinates. There is parking for 1 vehicle just north of the bridge only a few yards away from the first part.
The first part is of this multi is (I believe) completely unique, so well worth a visit! It is at the coordinates listed above and you are looking for a jar of coffee hidden in the crash barrier, the lid doesn't come off and you can't get inside it (SO DON'T TRY!), Once you've found the jar, press and HOLD the green button, the electronic device will flash a coded light sequence which will indicate the coordinates for the second part. You can remove it from it's home while using it but please replace carefully when finished.
HINT: You will need the help of a Jaguar driving TV detective from Oxford!!!
The second part I'm afraid is just a normal boring container, very easy to find on the only possible host at the given coordinates.
I'm not a great fan of multis but could not place a cache like this without having two separate locations. I hope you enjoy finding it as much as I've enjoyed setting it up.
