A Bonus for those who have done all the driving and hard work and completed both sets of my Humber Estuary Viewpoints Adventure Labs.
The true location is not too far away from where it is shown on the map and roughly between the 2 sets of Adventure Labs
For those that have completed the Adventure Labs already, the bonus numbers are now in the journals of the Labs.
This should enable you to work out and check the correct co-ords from home ready for when you are in the area.
N 53° AB.CDE' W 000° FG.HJK'
A pen will be required.
