I agree with what both of you are staying. Marilyn, here in Decatur, Alabama, folks often say, when you ask where someone lives, "Oh, he stays over on third Street, just down the block from the Baptist Church." It's part of their vernacular. My former mother-in-law lived in Richmond, VA. She'd say, "Alan, can you carry me to the store, my car's not running very good."
I've decided to write as my characters would speak, given their culture and location. Here in Northern Alabama, about half of all sentences start with "I'ma fixin' to ..." as in "I'ma fixin' to go to the store. Can I pick up anything for you while I'm there?" Seriously, it's probably the most common start to a sentence in the area.
Another one I hear almost everywhere is making a noun into a verb. I've been in the music biz all my life. I recently had a guitar repaired. I called and asked if it was almost finished. His answer" "We're efforting to have it done by tomorrow." Hmmm. I always thought it was We're making an effort to ..."
There are many more. I just shake my head and think "I'm far from brilliant and make a shitload of mistakes everyday, but give me a break!
