It's snowing! Not a lot. Just a dusting. And it's not really sticking at my elevation of 1,300 meters.
In light of the weather, my karate teacher Roland, who happens to be an automobile aficionado, reminded me that it is dangerous to drive with summer tires, even if the roads are clear of snow or ice. He said that summer tires are made to only be effective at or above 7.5 degrees Celcius (45.5 ºF). He says that summer tires will not grip the road properly at temperatures under this limit. Not only will tire performance be greatly diminished in curves but also when traveling in a straight line. They will not grip when one attempts to stop. I double checked, and he's right.
So, that's why my car is at the garage.
