Born in Shoreham in '54, went to Port Jefferson High, Southampton College '73-'74, got married and lived in Ridge until '94 at which time Grumman closed the Calverton facility and I moved down here for work. Suffolk, as a rule, is still pretty decent, but western Nassau is the pits. Much of the farming on the East End is gone, replaced with wineries. Can't drive 2 feet down Sound Ave without finding one.
Interesting too, the Hamptons of socialite fame, Southampton, East Hampton, etc... are just 30 minutes from Riverhead.
You're right about that very old cliche about pizza and bagels. Nobody does them better than NY and LI (no disregard to NJ fans...). My fav bagel place is, coincidentally, in a new plaza in Riverhead. They make the best egg bagels, and I usually bring back 2 dozen or so and freeze them.
Still had family in Miller Place until recently, and friends in Calverton, so I was up there pretty frequently. Things changed, haven't been up in about 2 years now. Really miss the food and the beaches. Thinking of getting a summer place up there. Yeah, the culture does suck, but really no worse than anywhere else.
