I've NEVER heard decade pronounced any other than DECK'ade. If JFK pronounced it differently, I never noticed. (Guess I should listen again.)

Used to get a kick (since I lived in Milwaukee until I was 20 when I moved to the Boston area) out of hearing all the Rs removed from words (such as the infamous "pahk the cah in Hahvahd yahd") placed on the ends of words such as Cuba. (Well, he had to do SOMETHING with 'em.)

Regionalisms fascinate me -- since I grew up with so many of them. "Bubbler" for drinking fountain (only in Milwaukee and some neighborhoods of Boston); ruff/roof pronunciation; both soda and pop (or even soda pop) -- "tonic" in Massachusetts; the differentiation between soda crackers and saltines in Massachusetts, but just soda crackers in Wisconsin; purse / bag / handbag / poke; bag / sack; chuck holes / pot holes; ant/awnt, etc.
