It's not that hard to say.

I have heard so many wacky and weird pronunciations of "Glasgow" in the last three days that yesterday evening, I snapped. I e-mailed our local news networks to explain to them that "Glasgow" does not rhyme with cow. I didn't even bother with the subtleties of the first syllable; it's more like "Glaz" and less like "Glass", but not quite either one. I thought that was best left to an in-person discussion when I get really agitated and start storming the studios. With alliteration, apparently.
