Going OT for just a second here: In case you aren't aware, there are seasonal TRO's on almost the entire South Cambs network from Haddenham right down through Oakington and Rampton. Probably due to 'laning' similar to that mentioned.
There was a bit in a Cambs newspaper recently saying that 'offroaders' had cut gates dowen in order to access the lanes out of season. Please remember that the police now have powers to seize and dispose of vehicles reported on closed greenlanes.
Sorry, back to the topic.
