I was west of enid yesterday on my way up to run the bird dog. I get past the Ringwood turnoff where it goes back to two lane. I get behind a welding truck that's doing about 50mph. I pass as soon as I get a chance and just in time for a large sheet of ice to fly off the top of his welder. I instinctively duck as it comes right for my drivers side window. damn! it was loud and I thought for sure there was some damage or a cracked window. I got lucky but it scared the bejeesus out of me!
