In Portland, Oregon, Christmas trees have been installed at Pioneer Courthouse Square annually since the public space opened in 1984. The trees have been donated by Stimson Lumber Company since 2002, and are delivered the week of Veterans Day (November 11). With some exceptions, the trees are 75-foot-tall Douglas firs, decorated with thousands of multi-colored LED lights.
Tree lighting ceremonies are held annually and have been broadcast on local television stations and streamed online. Many have included sing-alongs led by Thomas Lauderdale and other members of Pink Martini, with additional participation by other local music groups. Among mayors to flip the light switch are Tom Potter, Sam Adams, Charlie Hales, and Ted Wheeler. Portland has also seen tree arrival ceremonies, as well as a protest about the tree staged by Lars Larson in 2005. In 2010, a man attempted to set off a car bomb at the lighting ceremony.
