The container is slightly larger the your average micro and is
often referred to as a "Friedel Micro", its a strong plastic tube
containing just a log, pencil and a pen.
The location is little known wooded area called "The Church
Gresley Plantation" which can be accessed easily by road
(coordinates below), paths are unsuitable for wheelchairs and
buggies but its a great place to take older children and dogs
(although small dogs may get lost in the undergrowth).
The difficulty rating is a little higher due to tree coverage, I
had quite a hard time setting the coordinates for this one however
I am confident you should get within 20yds. If needed the spoiler
photo and the hint should point you in the right direction.
