I guess I'm a fair weather commuter.
I don't like to ride in the morning if it's much below 25F, or if it's rainy or snowy/icy.
I got a new job last Nov, 4.5 miles away. I work a 4 day week (32hrs) right now, going to 5 days/40hrs eventually. I ride 3-4 days a week nowadays.
I missed riding 3 weeks this winter because of cold or bad weather.
Our weather here is generally mild and dry so I'll ride most of the year.
