It started out sunny but chilly, I had shorts and short sleeve jersey and no extra layers, but climbing makes you warm, so i went up several miles until the clouds came in and the temp dropped and it started snowing. Nothing quite like being wet and descending in the cold. Hypothermic at the bottom and I was sick for a couple weeks.
After that I carried extra layers when climbing in cold weather. I sweat so much when climbing even in the 30s so I'm always soaking wet when the descents come after a long climb.
