After my brief interlude in Minnesota — it seemed like a fevered dream, almost a fantasy — I returned to Santa Rosa where I discovered the temperature was not expected to rise above 55 degrees Fahrenheit today. In bone-chilling, life-threatening conditions such as that, my Gopher State host, Greg, never rides his bike. He just dozes by his fireplace and guzzles mug after mug of pumpkin spice lattes delivered by Uber. Hence, I was tempted to emulate him and stay indoors during our cold snap. Instead, Old Grumble-Face hopped on two wheels and braved the brutal California elements in order to demonstrate how cold weather can be tamed.
