Hello Judy, Thank you for answering. I had a great aunt and uncle who went from Portland, Oregon to Vancouver, Washington to get married in 1920. I thought they went to Washington because there wasn't any 3 day waiting period.
I remember reading an article in one of the Portland newspapers, in the early 1900's, about Washington not having a waiting period. I think it was dated sometime between 1910-1919? The Washington laws must have changed, before 1942, when another great aunt, a resident of Washington, got married in Idaho.
