I got that a few times in Baltimore and I was no way. I always felt like people from the NJ/NY area talk without an accent. The west coast doesn't seem to have accents either. The most obvious accents are the Boston/New England accent, the southern, then maybe the Minnesota nice accent like in Fargo, which I feel sounds almost Canadian. Other than that, All the places I've been talk fairly normally, but I've only been to the 4 corners of the country, Florida, Maine, Oregon, California and they lack accents imo.
