re: Anyone here attempted to learn Cajun French?

my grandfather grew up speaking French but moving to BR as a kid resulted in him getting it paddled out of him at school - damn shame.
i have a bro-in-law that grew up down-bayou (he's a doy oui), as in any further south and he would be a soft shelled crab. most of the indian kids (will the word "sabian" get me banned?) still speak French at home.
