I cannot, for the life of me, understand why I signed up to do this bit about Colfax County. I do not have a good story to tell. I think my brother and sister-in law once lived in Clarkson or Howells, which are both in Colfax County - the only thing I remember about that is they could not drink the tap water because of high nitrate content.
There were 10,515 people in Colfax county as of the 2010 census, and the county seat is Schuyler. Both the county and the county seat were named after Vice President Schulyer Colfax, who was VP under Ulysses S.
