The attached PDF file begins “For the second year in a row, the Sun shone brightly on the annual NASS conference,” even though it was held at the University of Washington in Seattle.  A large number of sundial related displays, outdoor demonstrations, and a local tour of Seattle area sundials provided “hands-on” experience for the conferees.  Woody Sullivan, conference host, described the “hands-on” experience of designing and building the large vertical dial on the Physics and Science building.  Len Berggren presented history of gnomonics in medieval Islam, pointing out that the time of afternoon prayer is defined in terms of gnomon shadow length.  The Seattle tour of sundials included the analemmatic sundial in Gasworks Park, dials at Billings Middle School, and the Webster Park Equatorial Sundial among many others.  See what you missed, and download the PDF for all the details.
