This is one that gets me while traveling also...mispronouncing the name of a town.

For instance: Philadelphia to the locals is "Philla-lephia", said quickly. Or just plain "Philly". Trenton, NJ is "Treton" no "n' sound.

I was corrected for this one in New England: Haverhill pronounded "Haver(long a)ill", not "Haver-hill".

And of course, the Big Apple is "New Yawk".
