I usually spend weekday mornings on my couch with my leg extended and doing physical therapy on my bionic foot, with my local NPR station and Facebook. A couple of the on-air personalities are buddies (have met them in real life, and we would/have recognize/d each other meeting on the street).
Today I posted The Michigan Accent & Michiganders' Slang Words which claims "Pontiac - This is pronounced pah-neeack, if you say the "t" sound, you will give away that you're not from Michigan." Nope. The writer did not grow up a few miles from that town, nor did her family evidently drive that make of GM car.
Almost immediate my newsreader buddy reported on the school district in that fair city, pronouncing its name correctly. Of course I mentioned this on a post, and for the next read, he said "pah-neeack" followed by a teensy bit of dead air.
Such fun.
