The East Coast may be referred to as "the r-less corridor by linguists," but New Jersey speak has a very strong r. I learned this when I got to college. Someone mentioned a New Jersey accent. What? Yeah, New Jerrrrrsey.
We also said "laig" for "leg" and "aig" for "egg," plus "ditten" for "didn't" etc. Cyu-pon, garadge, rad-itator, not to mention all the non-U vocabulary.
As I love to point out, New Jersey has several different accents. The "Tony Soprano" accent is actually rare outside of folks raised in Hudson County. The classic North Jersey accent, IMHO, belongs to Mr. Anthony Bourdain of Leonia, and it sounds NOTHING like anything spoken east of the Hudson.
When I was in Lawrenceville (in the middle of the state, near Princeton), I was basically at the cut-off point between North Jersey and South Jersey accents, usage. Once you get south of Hamilton/Trenton, you start hearing folks drinking "Werter, " rooting for the "Iggles," and ordering "hewgies" instead of subs.
