A 35mm film container containing the log and a pencil only.
The cache will be easier to find in winter (or at least when there are no leaves on the trees - perhaps a bit of a hint there!). If locating at other times of the year take care, take your time and watch out for scratches and nettles (long sleeves perhaps best). I wouldn't recommend trying to find this in summer unless the hedges and verges have recently been cut.
There are lots of lovely walks around this area on quiet roads, tracks and paths.
