I was hauling my buddies offroad Toyota 4 runner down an ice road. Had to really give 'er up the hills to make it and then use engine braking down the hills. So Im following another freind whos flat towing his Jeep behind his F250 when all of a sudden his brake lights come on and his truck goes right, the jeep buggers off into the ditch, he is basically sliding perpendicular to the road blocking the whole road.......I barely touched the brakes and we start going sideways, this was a huge tankslapper, I was dancing on the pedals and somehow with a lot of luck, kept the trailer from sucking us off into the ditch or sideswiping the truck. This was the scariest moment ive ever had, I was so busy trying to keep the rig straight I never noticed that the trailer was actually jacknifed at one point, my buddy said "holy **** man, I knew we were in trouble when I saw the Yota out of the side window. The reason my buddy had to brake, there was 2 inbreds who decided to stop and have a chat just beyond the crest of the hill.......only problem, instead of pulling over and parking behind one another, they decided to just park side by side so they wouldnt have to get out in the cold.
