Filmed 1 mile from my home,11 miles east of Cheyenne Wy. F1 classified tornado destroyed pole barn, injured horses, flipped trailer and damaged siding and broken windows on a house which was right in the debris path.If you listen close enough you can hear the sound of the tornado as it hit the pole barn. The tornado crossed I-80 at MM375 The debris was strung out about 1/2 mile. I witnessed it from funnel to rope out stage. Too close for comfort
