So I met with one of the curators at the museum where I work. He gave me a long list (at least 20) of local New England possibilities for gallery/museum/educational showings for our beloved Periodic Table. I'm going to start gathering contact information and figure out which might be the best location, or the most receptive audience then start to send out letters of inquiry.
It'll take time, but this is going to happen. I feel it in my bones. :)
