In Martell, Wisconsin, residents are organizing to stop a new dairy farm planned near one of the best trout streams in the midwest--- the Rush River, about an hour's drive east of the Twin Cities. Opponents say a manure spill from the farm's storage lagoons could wipe out the trout in the Rush River for years to come. Defenders of the project say such fears are based on emotion, not science, and that large scale dairy operations are the way of the future in Wisconsin.
