Spent an hour to go 10 miles at 6am after a 12 hour shift. Not to shabby, for me! Alot of frozen rain with an irritating dusting of snow to make it slippery. In fact I lost my footing at a stop light and almost went over becasue my foot came out from under me. But it felt okay to ride on, carefully. Might be time to lose the Contact 2000s' on the MTB and sport for some studs. This is my first winter commuting and so far its been fun! Thank goodness I rode MC's thru more than a few Colorado winters. I have the keep warm thing down, just need to work on Ice confidence on a bicycle...
