Don't speed: Weeds ahead A snowplow pushes a mass of tumbleweeds off U-68 on the west side of Utah Lake near Elberta. High winds blew dozens of the weeds onto the road around 6 p.m. Wednesday. The tumbleweeds, which ranged from basketball-size to 3 feet in diameter, were caught between two fences and rapidly filled the roadway. The Utah Highway Patrol closed the road while two snowplows from the Utah Department of Transportation cleared it.
