But you could change in CT to I91 to I belive N Haven CT and 84 to Hartford CT. to I90 East in Sturbridge MA. Follow I90 east to Route 128 (I95). That will save you about 30 mins. Then to I93 north to NH and get off at Downtown Manchester NH. the National Guard Armory (car show site) is just minutes away from the exit, just ask anyone for Hotters wich is about a block away. E mail me if you need more details.
