8 July 2015 I was caught in one in Mill City, Nevada, deputy sheriffs closed down I-80, they made us pull off on to the exit ramp. Stood outside in that for over 30 minutes. Luckily, the wind, gusts of 60 mph, was coming from the North so, facing East, I stood on the side of a tractor trailer which helped block it. After it passed rode back East to Winnwmuca and grabbed a room. The one thing that was going through my mind was those pioneers in just a covered wagon crossing West, how did they do it. What grit and determination they had. Truly, an incredible people.
