It was COLD this morning! Our first impression of that was when we realized we had set the room thermostat to air conditioning instead of heating! But after a nourishing hotel 
Frosty truck window
hot breakfast (waffles, oatmeal, little omelets, the kind of hotel breakfast we last had in 2017) we piled into the truck which was covered with Jack Frost flakes (see photo). The thermometer read 18. On the road the speed limit was 75, but the engine was cold and wouldn't go that fast right away. But the sun was shining and by the end of the day the temperature was 38.
Most of Nevada is what the geologists call basin and range country, a brown color with desert rocks, in places cleared to make cattle pasture. The only trees are (a) in cities or on irrigated ranches where they've been planted or (b) dark green evergreens high in the mountains above tree line, which in this case means where there's enough rain or snow fall to nourish the larger forms of vegetation. For the driver in January, the clear air often provides vistas of ten or fifteen miles, with mountain ranges in the distance at forty or fifty miles away. City dwellers are often disconcerted by their views of basin and range country. Today we crossed the highest mountain pass since California - over 5900 feet - and it was bone dry.
Wildlife crossing
The most unusual highway sight today looked like an unfinished bridge without a road on either side. It is a wildlife bridge across route I-80 with high fences on both sides to prevent deer from jumping off in mid-crossing. Flashing highway signs announce the presence of major wildlife crossings According to this website, thousands of mule deer cross the highway each autumn.
Our city friends drive small, fuel-efficient Toyota Corollas, and are amazed by our gas-guzzling half-ton GMC Sierra. But in Nevada pickups are BIG, suitable for towing heavy trailers and loads of hay; they have high road clearance and oversize mud and snow tires for off-road work. AND, the pickup is the standard personal vehicle for the locals.
We drove to Wendover at the Utah-Nevada border, the farthest eastern point of this trip. For our purposes - stopping at casinos to play slot machines - we visited West Wendover, in Nevada; Wendover is just across the state line into Utah and serves workers at 
Wendover Will
Dugway Proving Grounds and Bonneville Salt Flats.
Unsurprisingly, the casinos were all busy on this Sunday morning. Wendover is less than 2 hours from the Salt Lake City metropolitan area. Branches of urban megacasinos like Nugget and Peppermill rub shoulders with smaller local places. Customers range from college-age to senior citizens (we note that all the handicapped parking spaces are filled). On this day we think we saw more mask-wearing folks than on previous days, but that is a most unscientific sampling.
After a morning tour through several places, we stopped for lunch at a small café in Wendover for enchiladas. Then we drove back to Wells, first stopping to photograph Wendover Will, a forty-foot mechanical neon cowboy perched in the middle of the road, and returned to our warm hotel room, after a fruitless 30-mile detour in search of a ghost town.
