I thought about it more David and it was a dumb question. Duh. In the States we say 'Zee as in Zebra' because Zee sounds like our pronunciation for the letter 'C' (See), so we have to clarify. If you say 'Zed' it doesn't come close to anything else in the alphabet.
I still don't think it was a dumb question Delalluvia. If we don't ask, we will never know for sure!
I am constantly amazed at some of the topics we discuss here on this forum.... fish tacos.... "zed"s..... are blueberries really blue... the list goes on and on. Who could ever imagine?
But I guess this is why I like the forum so much. People are willing to discuss nearly anything, and somehow strange topics like these actually become interesting. Well, most of the time they do!
