I stopped and walked around the Neas House in Hanover, PA this morning.  In the two years I have lived here I have never found it open.  I even bought a ticket to tour it last year but have never been able to get inside.  I eventually lost interest after I found that they wouldn’t let me take any pictures.  It looks like it is well maintained for the benefit of those driving by.  You can read what the Historical Society says about it by clicking here.
