Tips for South Dakota Residents
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Gradually adjust your sleep schedule a few days before the time change to minimize disruption.
