At this point I had gone back and forth a fair bit, following my little satnav pointer, including heading down a couple of paths only to come straight back up them once I was sure I'd completed the un-done parts of the track.
I was a little weird, following this complicated little route. I felt a bit like a bee doing the waggle dance, or something.
