I am an out of stater that moved to Raleigh. I saw a lecture about the language diversity within the state here at one time on our public access channel by a professor from North Carolina State University. One thing I remember from this was that in various parts across the state these three words can all end up with the same pronunciation:

pin, pen, pan

all sounding a bit like "pe~an"
