At least you admint that. My first college roommate was from Suffolk New York. My goodness, here I am 17 years old from the south with very little experience from anything outside of Va, and my roommate spoke like that. I asked him one day if he ever pronounced R's.
But he really pronounced "I" 's . As in Five. He would say F "eye" ve. Really emphasizing the I. Uncounsciously I would pick up a little of that and when I came home on some weekends, my parents would question my pronounciatios....he was rubbing off on me and I didn't realize it.
