Sure! You betcha!

For an upper midwest accent, you gotta pin your checks tight in the corners of your mouth and only crack your mouth open a bit. Your chin and cheek muscles should kinda be pinned tight. For "R", words like work become weerrk, where the "O" sounds like an "E" and bleeds into the "R". When the letter "U" is preceded by an "H", the 'H" is often silent or blended into a "EWE" sound. Words like "Huge" become "Yuge" and the "H" is almost / is silent. "H's" followed by "O's" become a "WHO" sound. So instead of Human is Hooman. PNWr's do none of this. But the Canucks have screwed up your "O's" for certain.

When I moved to Michigan to go to college, I was floored by how retardedly charming the upper midwest + canuck accent and way of speaking really is. They all thought I was from Texas because I spoke with a drawl. Then I moved onto to South Carolina and that's a whole other level of retardation. Ah...the deep south. There is a reason I live in the exact opposite corner of the US.
