Although it's one of the best-preserved Roman forts in the UK I'm not that interested in it per se. It's the stone circle nearby, that I abentmindedly 'curate', that fascinates. There's many monuments in this valley and getting Google Map centred round about there is a big jump forward. I should be able to date the imagery by what is there and what's not. (A recent roadbuilding programme helps there). I see the satellites flying over - and the little stuff wanders over to have a look at my camp, singleseaters, microlights and rescue helicopters.
