Beautiful morning for a bike ride -- sunny , about 53 F (12 C), and little wind. Got about 1.5 mi. from my house and realized I didn't have my seat bag (spare tube, etc.). I'd forgotten to switch it from the bike I'd used for the last couple of rainy days. For 15 seconds I considered riding on, but then I figured that would just anger the Bicycle Gods, and so I turned around and rode back to my house, put the seat bag on my bike, and headed back to work. Like I said, a beautiful morning for a bike ride.
