On April 7, 1968, a memorial gathering for Martin Luther King, Jr. at Casper’s Natrona County High School drew 750 people. On April 8, 1890, an election for the county seat of Natrona County brought in 296 votes for Casper and 697 votes for Bessemer. However, Bessemer may have had as few as two dozen residents at the time. So the organizing commissioners ruled the Bessemer vote was fraudulent and awarded county seat status to Casper.
