To add another layer of information to Dave Wells' comment about the two facilities at NMAI. Plans actually call for three buildings: the Customs House, the Mall Museum, plus the storage/study facility at (sp?) Suitland Maryland outside Washington D.C. I participated in a two-day planning meeting for NMAI a couple of years ago, and they also discussed what they call the Fourth Museum, which a museum without walls on the grandest possible scale, a virtual assemblage of hundreds of tribal nations linked by technology. In some ways, they felt that the Fourth Museum was the most importa nt..... This is not new info, the technology consultation meeting was a while ago. If anyone from NMAI is on line, it would be very interesting to learn what has happened since then. Ann Mintz Orlando Science Center [log in to unmask]
