Oregon has no legal distinction between “town” and “city” — every incorporated Sherman County municipality is chartered as a city regardless of size. Biggs Junction, at the north end of the county on the Columbia River, is the county’s main travel-service stop at the US 97\/I-84 interchange rather than a residential settlement, which is why the Census Bureau has never tracked a population figure for it.<\/p>\n
