I found it really useful. First off there were a couple of brand new fence lines that weren't up there last time I was there. And secondly I was really pleased to easily find the quad bike tracks after Deepdale that take you down to the Middle Tongue checkpoint, especially in all that snow. And then, after that, our line from there to the Hell Gap to Cray track wasn't too bad either (despite me referring to it as heading 'west' when of course I meant east)
