After finding No. 3 in the series carry on along the footpath towards the main road (A25) and you will soon arrive at GZ.
Don't forget to bring a pen or pencil to sign log.
Did you spot the railway line or a train? just to the NE.
There is also some more important information hidden in this container.
PLEASE REMEMBER NO VEHICLES ARE ALLOWED ALONG THIS SECTION OF THE FOOTPATH.
Good Luck.
