As I headed West on hwy 50. I noticed two crafts hovering on both sides north and south of the highway. There was 3 cars in front of me and 1 behind me. The crafts made no noise. As they rose up they began to strobe brightly white lights, strobe, strobe, strobe.I was following the craft flying from the south across the highway to the north. I could never get a good look at the object, due to the bright lights strobing. By the time I had gotten to the first stop lights, out of town, I was blinded. I hobbled my way back home. For days, my eyesight was messed up and I could not handle any bright sunlight or the tv colors. At first, I thought it was a stealth bomber. I later found out that the stealth cannot hover, they are made for speed.
