If you’ve driven long enough, you have seen the highway in front of you made impassable by any number of things. Snow. Flood waters. Bad-driving four-wheelers. Fog. Any manner of wildlife or livestock. But, on Monday, May 21, US 395 at Gardnerville, Nevada near the California state line was shutdown by, of all things, a 5-foot-high wave of mud. The highway has been reopened.
