Ice scares me! That's why I live in Phoenix now. But if I lived back in the snow and cold, I would skip an icy commute. I need all my body parts functioning to do my job, so I am careful in the risks I choose to take. A rocky downhill where I can keep my bike under control: OK. Black ice where control may be impossible: no way--especially on the road where cars might be out of control as well!

Why do you commute? To save money? For the pleasure? To keep in shape? What would it mean to skip the commute? What would it mean to take the risk? What are your values? And, is there anyone else you need to consider? If you were hurt, would it affect anyone else, eg. SO or children?

That being said, I hate when I plan rides around the weatherman's predictions, and then he is wrong! So I share you frustration on that score.
