Northern Nav Ex issues

[NorthernRaider]

Ok, for those who expressed an interest in the ickle Northern Nav Ex I think I may have the foundations of the exercise laid out, but I dont know whether to start or finish at the northern end, So please bare with me a while longer. Ideally it will still be fairly simple but driving in moderately remote areas and being the first so far it will only have a cryptic start point, a six figure GR for the check point and a cryptic end point and hopefully a BBQ or somefink to finish.
