Most are but there are a few that aren't. Certainly the one at Cock Hill and the following two on the east moor are. Shackleton Knoll isn't nor is the one at the top o' stairs.
Thanks Bob.
So at the checkpoints that aren't manned, I take it there will be some way of proving that you have been there. Also, are the unmanned points obvious and easy to find (Providing you're in the correct place)?
