CAJUN ACCORDION DISCUSSION GROUP
An interesting point of Cajun French grammar (also in old French), inanimate "qui" -> http://www.aclacaal.org/Revue/vol-9-no2-art-rottet.pdf, p.4/20, (2) et (3).
What's odd is it's common in the far north west part, and the far eastern part of Acadiana, but not in between.
