I had never seen one of these before. I saw it enter the pattern and thought to myselff,"Self, that looks odd." Sure enough, it was strange. It is a two-place Pawnee owned by the Wilamette Valley Soaring Club. These guys operate out of the North Plains Glider Port (Oregon) which is owned by my father in law. Its designator is 1OR4. It says that WVSC owns the glider port, but they just operate it.
