Long-term readers may notice a few new locations creep into our photographs following our move from Castle Cary to Dorchester.There was only so much we were able to do there, and West Park, Castle Cary certainly wasn’t the most attractive backdrop in the world. Now we have golden beaches, urban junctions (even traffic lights!), two railway stations and a good choice of tree-lined avenues to choose from. Less satisfactory is the loss of our long-established test circuits and the famous test hill, used for recording rolling resistance from our very first issue in 1993.When things calm down a bit,we hope to establish suitable replacements,but for the time being some data may be incomplete.
