So the weather finally broke to the point it was time to put on the snow tires. All went well with the exception of one airless tire.
I drove to the station that has a free air compressor and filled it up. Since the place was well lit and was on level ground, I went ahead and mounted the last two tires.
While mounting the tires I here this whistle in the cold darkness. One of those “hey, over here” attention getting whistles, again and again. It gets louder and louder until a random stranger pumping gas yells out “be positive!”. Then the whistling stopped.
I looked out across the road and saw the shadow of the flag and the wagons of “the wagon guy” and said to myself. “of course!”
