i have seen this trackable today cant remember which cache it was in but it was on Ilkley moor when i was doing 'The series of tens moor walk' i
GC2V7XK this should help you locate the area
I found it after the earthcache just before no.1 and before the ba tat box (i did them in an anti clockwise route)
I can also tell you i found it 9 minutes before i found the bah tat box so im guessing duke of cambridge or just in passing
