On This Date in Minnesota History: December 1

December 1, 1982 - Minneapolis-St. Paul implemented a 911 system on this date that was reportedly the first multi-county Enhanced system in the country. It served the seven surrounding counties of Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington. The system was later expanded to include Isanti and Chisago counties and is still, geographically, the largest Enhanced 911 system in the country.
