Just an 'advisory'.
Two of us on motor bikes stop to watch some airfield maintenance today and. my mate was using Binoculars. A police car arrived and the officer asked, who was using such ? my mate said it was me. The officer stated that he had been seen on the Base camera and sent round to check us out.
This proves that they are watching us, other wise...no problems

Finally, I did mention a nasty metallic rattle coming from his Police car, the exhaust was hanging of ;-)
