Bubble-boy

Regarding the "Bubble Boy" episode: When Jerry and Elaine are driving upstate and they lose George and his girlfriend, they are traveling along the Taconic State Parkway in Dutchess County NY. I live about a mile from the exit where they got off and went to a diner and I can happily report that the people there are friendlier than portrayed ("There's the guy that tried to kill the bubble boy. Get him!") It's a nice drive for the truly devoted Seinfeld fan. I won't tell you the exact exit. Try to guess!
