When he was a little baby, he lived at 516 13TH AVE E, Seattle, Washington, which is a few blocks west of the Hopvine for those who have lived on Cap Hill. The link describing the location and time frame includes a photo of the property.
I was over at the archives hoping the Skagit marriage records had finally been put up (they are listed as "coming soon") and saw the article. I lived for several years less than a mile from that location, altho obviously decades after the future president had moved on.
I miss the Hopvine. If you go there and have a beer and a sandwich, think of me.
