Maybe it's just because I spent the first half of my life living in the South, where winter driving rarely was an issue (generally didn't snow or freeze, and when it did, we all stayed home).  For some reason, I've never gotten comfortable driving at more than in-town speeds on Wyoming highways when it's wintry - you do it out of necessity, but it's always a white-knuckle affair for me.  Without fail, I'll be blown off the road several times by pickups, SUV's, and 18-wheelers driving like it's a clear summer day.

Next time I'm slow-poking down I-25, I bet I'll have company - at least this guy.  Check a pretty amazing video of a near-miss in winter conditions - where the driver emerged unscathed, although I'm betting he needed a stiff drink and a new pair of pants.
