The US is so large, that every state and sometimes county or city within a state has its own culture and dialect. There is a website called "slanguage" where people can post the particular curious sayings of their city. I have friends who are an elderly couple from England. They have visited Montana several times, and questioned me about why we say things "wrong" (of course their way is the correct way ;-) ... in particular the difference between a robin and a thrush. I also went shopping with the lady, and she was quite amused when I called a waistcoat a vest. The states of Montana, Idaho, Wyoming, Utah, Colorado, the Dakotas, Oregon, and Washington, have a relatively similar American dialect, which is similar to the Canadian provinces north of us (eh). The actor Gary Cooper was born in Helena (where I was raised) and his speech was like the average farm, ranch, small town Montanan. Yup. Nope. Television and the migration north of Californians has changed our speech somewhat, but a small town or ranch person still speaks like Gary Cooper. (Like my Uncle Gene McConnell, who lives in the woods and still "rolls his own". ) Here we call a ditch that is along a road a "barrow pit" and at the turn of the century, cowboys would describe something that was good as "boss" or "out of sight". Those two phrases re-surfaced in the surfer/beach boy era. I'd love to add more, but it's Monday.... better get back to work.
