So today I went back to Mill Wood to try and resolve how all the various tracks join up. According to my GPS I should be withing 10ft or so of reality when the sky is clear of trees, and between 20 and 30ft out in case of tree cover.
On that basis my mapping of the car park area and the surrounding tracks/paths should be pretty good, but it still looks a bit confusing around there. I think at least one more visit will be required to finally solve the mystery.
I have heavily edited that area, including things I added last time and also one path rollercow added. They now join up in the way that things appear on the ground, even if the actual location might be a bit iffy.
I'll try to take another track on the road at some point, preferably on foot since in a car the steep sides of the road at various points makes the signal rather poor I'd imagine.
I've added St. Andrew at Penrice and I need to go back again there to add some more tracks and things over that side as well. Still plenty more tracks to explore down in Mill Wood too. They are well sign posted which makes a change.
