Well, I'm back. I rode for 45 minutes. Current temperature is 25 degrees Fahrenheit. And I'm so overheated that I've opened the window to my office. I've come to realize that getting the lights, reflectors and other nighttime safety gear for my bicycle may have been the smartest move I've made in years. I've rediscovered the self I cultivated between my last year of high school and the time when I moved into Bay Area neighborhoods where a late-night exercise regimen was not wise for a suburban white boy to undertake. Yes, I'm up late. But the payoff is worth it.
