OK, the Fremont Market wasn't located in Sabin, but very close. From the mid-1940s till the late 1960s, it was situated on the southwest corner at the intersection of Williams Avenue and NE Fremont Street. The market included an old-fashioned butcher shop and the owner, John Sinner, was famous for his German sausage. The site is now a New Seasons Market, which periodically makes and sells sausage using John Sinner's recipe.
