Route 9 Haiku Group is a small, exclusive local haiku group based in the Capital District of Upstate New York. It was founded in 2000 by Hilary Tann, Yu Chang, and John Stevenson and later joined by Tom Clausen and Ion Codrescu. The group meets monthly, usually in the Tai Pan restaurant in Halfmoon, N.Y., which specializes in dim sum (Chinese dumplings), and which in turn suggested the name of the group's biannual haiku journal, Upstate Dim Sum.
