And I feel I should take this a bit further and recommend you start shopping for your studded tires now. You won't have as many options in December.

I run 500 lumens up front, and about half that in the rear, with some blinkies scattered about the sides and rear of helmet. Since I leave at 5:30 am, lights are essential to extending my season. Nite rider tri-newt, as well as Dinotte, are worth the hefty price tags.
