Is it naive to hope that "Cirencester" is pronounced "sirensester"? Or is it one of those English things where it's pronounced "cinchister" or "sinister" or, for that matter, "metal polish"?

There used to be a "sister" school of thought, but I've never heard it from a Glos native, so perhaps it was one of those British upper-class shibboleths, or another sad victim of universal literacy. We've mentioned the matter in AUE, I believe.Mike.
