I've been told I have an accent, but that was by an Aussie..
I grew up in Northwestern Indiana, which has a bit of a Chicago type accent..However I have lived in Central Indiana since I was 21 and have picked up a little bit more of a 'southern' dialect.. My dad told me he could tell I spoke differently after moving down here.
I used to talk to a Canadian quite regularly and I really liked his voice and colloquialisms.. He lives on the 'wolfs head' of Lake Superior.. Another guy I used to talk to was a Canadian who had lived in GBR for a long time.. I expected an English accent but he sounded like me..
