RedCableTie: I went to check the cache following discostu321's Did-Not-Find - and have decided to archive both of the GWR and the Romans caches.
These have been my most troublesome caches. #1 has now had its tree cut down twice - on both occasions the cache box was found nestling in the horizontal tree. I found #2 with its box open and the contents strewn across the ground - for the second time. So, I think after 4+ years these caches have had their day and I will archive both of them and let someone else use the area as it is good caching country.
