- not being hot
- not needing to carry a water bottle for a 10mi trip

That's about it. So glad to not have to deal with shoe covers, layers, jackets, balaclava, gloves. We only had a few weeks of "real" winter here, but that was enough. I'm not complaining though - only 1 week of anything frozen on the ground and I was able to ride all winter long without resorting to snow tires or any of that. I think the most annoying time of year is when you need gloves and jackets and such in the morning, but its 85 on the way home and you have to haul all the bulky junk home.
