For those interested in this subject, this is a pretty interesting blog, all done in one page, with lots of links to other pages. Be sure to check out the dialect of the author.

It should be noted that the Miles City, MT, area has its own dialect.

Warning: it will take you about a month of Sundays to completely "absorb" the linked post. Good luck. Have fun.
