A semi traveling westbound on Rt.120 in Round Lake crossed the center line and hit the rear wheels of a semi tractor going eastbound and then proceded to hit the car traveling behind the eastbound semi knocking it off the road. The other cars in the path of the semi were able to drive into a field to escape the truck taveling in there lane. The truck then somehow still continued down the road for about 200 yards before digging into the dirt and shrubs behind some homes. The driver of the car that was hit by the semi received bad injuries to his arm which was resting on his door during impact. After Round Lake RPD firefighters extricated the victim he was flown by Flight For Life to Milwaukee to try and save the mans arm. There were no other injuries in this crazy wreck.
