Or it could have been super cold and powdery so it was just scattering as you drove. Happens a lot here and I imagine in Colorado too. I doubt there was significant accumulation...just no way it would have blasted through with no slipping. Seriously, I don't consider myself a snow driving God by any means, but my Dad did make me learn (fairly extensively) to drive on snow and ice in a RWD car before I even had my license and I've been driving for about 25 years. Snow + 2WD truck = BAD news and a truck based SUV isn't much better. Add the high center of gravity and it's a disaster waiting to happen. I've said it before and I say it again; my Xterra is a handful in 2WD on compact snow and ice with A/T tires, even at very slow speeds.
