Here's very interesting site where someone has mapped North American dialects. You can click on an area and You-tube links are shown where you can hear the spoken dialects.
According to my SIL, who has a degree in linguistics in addition to computer engineering, we do have a quirky use of words in Central Illinois. In most parts of the country "any more" is used in the negative (i.e. I don't want any more), but in our area we also use the words "any more" in the positive to mean "nowadays" (i.e. Any more I enjoy doing that.). So we don't have accents around here, but we like to rearrange words to keep people guessing what we really mean.
