There was many objects stopping traffic on a major highway outside Monterrey, MexicoMy brother's girlfriend, her family and many vehicles along a toll-highway, (the equivalent of an interstate), viewed an extremely large craft in the night sky. She told us that the illuminescence of the craft was extraordinary. A "bright white light". She informed us that there were other smaller crafts "of light", different colors, oscillating and circling the larger craft. She informed us that she called my brother via cell phone as it was happening. The younger child in the vehicle was frightened. They pulled over and exited the vehicle. They told us that there were other vehicles pulled over on the side of the highway watching the crafts. She took pictures of the crafts. However, out of a roll of 20+ pictures, they all came out fine except the ones taken of the craft. Those appeared just "white". She did inform me that approximately a week before one of the same sisters saw a strange craft (ufo) in the night sky. Their home in Monterrey Mexico is basically on a mountain. From the expanse of their upper middle class home you have a view , panorama, of the entire city below...A million plus. Their living room is one long window overlooking the city. She tells me others she knows have taken video. She wants to look at it to see if it was the same thing seen. She is sane, yet embarrased. She told me she never believed, until now. My brother and I live in McAllen, Texas, approximately a 3 hr. drive from Monterrey.((NUFORC Note: Date is approximate. PD))
