Hmmm. Having just chugged the snowblower through 12" of the white stuff
last night I'm surprised I forgot about the snow. Definitely brighter
than sunny 16. But I'll only spot you one stop so I'd say only 1/250
and not 1/500 or 1/1000. I'd go out and measure the stuff but it's
pitch black at the moment.
