This morning it was in the SINGLE digit, meaning it was actually 1 degree. I have skied in tempertures this low and its not fun even if your dressed for it. I can't image trying to bike in it.
I have been watching the Hill Slug Chronicles with some envy as it seems that even in this cold weather they are riding and having some fun. I don't have the cold weather gear or mountain bike to join them but if the cold weather continues to keep me off the road I may consider it.
