2/3-6. First Portland Winter Light Festival. Reasonable success, judging by the attendance. I happened to have time Friday evening, so I went despite of the rain.
The river cruise company Portland Spirit offered free passage twice on each side (once more on Saturday evening). You can purchase meal and drink on board. 2nd floor had a few singers from Oregon Opera who performed arias at times, in front of noisy audience and runaround children. Lots of people on board, but not a lot get on board. Maybe it's too rainy that people just stay in the boat going back and forth. Certainly the Willamette River is quite pretty at night.
Most light installations are around OMSI. Maybe about a dozen, plus some projections and two wood burning stoves. The rain creates reflections of the lights. 10 minutes is enough to see all of them. Need more for next year for me to come again.
