Each month, the Oregon Encyclopedia hosts History Nights at McMenamins Pubs in Portland, Troutdale, and Bend. At each History Night, the OE looks back at the people and events that have shaped our communities. History Nights are sponsored by the Oregon Historical Society, the Des Chutes Historical Museum.
