Last Friday night, I was dealing with a kidney stone. If you’ve never had one, it’s sort of like trying to pass a large cocklebur through a swizzle stick. Your back hurts. A lot. It is very hard to calm things down. So I ended up climbing out of bed and heading to the emergency room for some pain medicine. And as I was driving, a soothing sense of calm came over me. And then I realized, it was because of the vehicle I was driving: a 2014 Chevrolet Traverse LTZ.
