After touring the historic Washington monuments display and the NPS tribute, we (or more correctly, I) decided to also see the model train exhibit, which in reality was a series of re-creations of iconic national parks and sites in the National Register of Historic Places, all made from plants and other natural materials, with some model trains running through, around or above them. I must add that this exhibit was staged in a darkened gallery, and the lighting was in very unusual colors.
This is Freedom Tower National Historic Landmark in Miami, Florida, considered the "Ellis Island of the South” for its role from 1962 through 1974 as the Cuban Assistance Center, offering nationally sanctioned relief to the Cuban refugees who sought political asylum from the regime of Fidel Castro.
