I love riding on a warm, sunny day, but some of my best rides have been in rain and on snowy roads. If I restricted my riding to what some here would consider good cycling weather, I wouldn't have that many days on my bike. I'd have to get off when it's hot or cold or windy or rainy, but those days are all part of the more complete experience of riding a bike.
It is possible to have days when it's not good to be out on a bike, but those are usually the days when it's not good to be in a car either.
