Some workers received the day off, including these employees of the Northwestern National Bank. When the polls opened they fulfilled their obligation as voting citizens and cast their ballots, then took off in cars provided by the bank club for Bonneville, Oregon for "sports and dancing."
Oregonian, May 21, 1920, 4.
Before the Bonneville Dam was constructed the area in Multnomah County was popular for picnics and, evidently, sports and dancing. On its website the Salem Public Library has a beautiful digital image of Bonneville taken in 1915 from the Oregon State Archives collections.
Dancing and voting: sounds like a great tradition to perpetuate.
