Dartmoor's a tricky place in mist as thick as it was last night.
As you gingerly make your way over ground that is normally so familiar there lurks a gnawing doubt.
Should I turn right here or is it a bit further on?
I don't remember this kink in the route, or that wall.
On Wednesday night, good navigation and timing are very important.
What relief. I can see the cars.
And it's only 7.28 pm. Now for the walk!
