One thing I like about the radio program Car Talk is listening to the different accents and manner of speech of callers around the USA. One call will be from Maine, and the next for New Orleans. I think it’s entertaining just to listen to the difference in the caller’s language and speech style.
If you have a few minutes spare time, this NY Times quiz is a hoot. It promises to narrow down where you hail from based on your answer to 25 questions about the words you use to describe various things. You know that little garden bug that rolls up in a ball when you touch it? What do you call it? A pill bug? A potato bug? What you call it tells something about where you are located. I was surprised how accurately it worked for me.
Takes about 10 minutes. Be sure not to give up at the end, it might look like it crashed, but just wait, it takes a minute or two for it to compute and draw the map based on your answers.
