text_A: Olmsted County is a fairly unusual of mix urban and rural areas in that there’s no transition or buffer between the two environments. Rochester, Minnesota’s third largest city of roughly 118,000 people sits in the Zumbro River valley at the center of the county. Outside the valley however, with the exception of a small amount of urban growth in the last few years, remains farmland with small agricultural based communities and no directly adjacent suburbs. Stewartville, the county’s second largest city, is slightly over 1/20th the size at roughly 6,000 people, an unusually large gap for a metropolitan area.
text_B: Would a person who lives in a city in Olmsted County probably have trouble finding a farmers' market?
NO.
