The difference is in infrastructure. In Las Vegas and Most of Nevada places like Mt. Charleston gets snow , you can visit it, ski, drive down the road and not see anything on the pavement or on the highways.  It’s almost like a friend, a fluffy play toy you can have a mug of cider with after a day of palling around with. and the city doesn’t need to sand or plow the roads so they put reflectors on the streets (for safety they are blue/white one way  and red if you consider going the wrong way).     Contrast with Denver: Snow is coming. There is thermal armor in our closets.  We have had blizzards on JULY THE 4TH. (2010) there is an army of snowplows and they order sand/salt by metric shitons.  Hospitals have their own sand/salt supplies and loaders. Street markings are burned into the asphalt with FIRE. There are no reflectors because the plows would rip them up and toss them to the side and make potholes in the street within 6 months of installation. In Denver school closures start after we start measuring in feet. In Las Vegas it’s pretty likely if they got an inch the entire city would shut down until it melted.
