I live in VA, but originally am from Jersy, the suburbs of Trenton. Been to the state archives and library in Trenton several times. As Trish said it is a wonderful archive. Also a very safe area, well patroled. They also have dedicated (free) parking. In a garage or just outside the building depending on the national security level color.
I have spent several enjoyable weekends in Cape May visitng friends. Ocean County is a beautiful part of the state.
