That's hilarious.
I grew up in the middle of a thirty-mile wide hemisphere of No Discernible Accent on the Connecticut shore. West of Bridgeport, and the Brooklyn/Queens/Lon-Guy-land accent would blossom. East of New Haven, the Rhode Island twist on the Boston honk would sound. But where I grew up, "strangers" from just 15 miles across Long Island Sound would sound like foreigners. My NY cousins were from a different land....... And whenever Mom and Dad got mad? They reverted -- instantly --.....
In Indiana ("the South's middle finger up the North..."), you can tell from which end of the state someone hales: southern accent? South of I70. No accent/Chicago whisper/Michigan Eh?: North of I70. Too funny.
Me? I am mostly camoflagued, I guess. 30 years here. But I can write Hoosier. You jus' use lots of apostrophes. Yep.
(Jus' sayin'...)
