It was warm out yesterday, but the sky was clear last night, and by
today's early light, there was a light coat of ice on my truck windshield
- but only the windshield, but not either of the side windows or
the rear window.
The truck was facing south east, into a sailboat, and was sheltered
by the house front too. It's a black '94 GMC truck. The prevailing
winds are either south which is warm, or north which is cool.
I think I know why it iced that way - can you guess?
