It doesn't get better than this morning, for me. Around 3 C/37-38 F, sunny, no wind, and a freshly-tuned bike (well, fairly fresh, anyway -- tuned it up this weeked). I wore shorts because Weather.com predicted it would be around 43, but I still wasn't cold. Probably looked kind of silly wearing shorts, a sweater, and gloves (my hands get cold easily), but then, I don't ride my bike to look cool
