[3] As a child, Robert Mills Grant rode his horse, Snowball, to school on the nearby CMD Ranch on Richeau Creek.
[1] Young Grant trailed cattle to Chugwater, loaded the livestock on the railroad, and rode with the herd east to the Union Stockyards in Omaha, Nebraska.
After his marriage to the former Betty Lou Nation (1923-1971), Grant established their ranch residence by moving a bank building from Slater in Platte County to the family property and then renovating the structure into a house.

He served five two-year terms in the House and bowed out in 1992 when Platte County was reduced to a single seat in the lower legislative chamber.
