The Seafair of Seattle. The back of the card, written in 1966:

Dear Folks:
Wow! What a day! We changed motels, I was interviewed by 2 employers, we have a prospective house ($150 per mo.) Marty will start Confirmation class tomorrow, all three will start school Mon in a Luth. School. This is a picture of the Motel we are now in. I think we’ll stay here while.

Perhaps he’s still there, forty years later.
