Glad to hear you didn't have any serious injuries. You might want to consider some studded tires for riding in the winter. I just picked up some 700c x 40 Suomi Nokian Ice Speed Tires last week and I love them! I have had no issue turning on glare ice with them and they don't have a significant increase in rolling resistance over my 700c x 32 Bontrager Hard Case tires.
