The deep reflective sense of the past is powerful. I can imagine how you must have felt. How purposeful to use rice in such a symbolic way. I thought that the postcard technique was memorable too. I wrote a letter to my mother on Guam. The ideal educator of the family, she would be touched deeply and would probably want to visit this museum on her next trip out here. I also wrote to myself [and my students] via Mesa Linda sharing my profound thoughts.
I may consider arranging a fieldtrip with my students.
