January of '91 I was stationed at Vandenberg AFB, CA, and had taken the wife and kids home to Michigan for Christmas. Heading back we went through the central route instead of through LA. Got to Mojave, where the airplane graveyard is, and the were terrible winds coming off the mountains, 30 mph steady with gusts to 60 but temps were in the 60s. Heading the 20 or so miles up to the top of the pass at Tehachapi, it was foggy as soon as the elevation started to rise, and the temperature began to fall. The road started to get icy, and traffic slowed to a crawl, but I kept moving in the fast lane since the right was full of truckers. the antenna on our '89 Caravan got to be about 1/2" in diameter with ice streamers off the back. Almost an hour to go that 20 miles, then we get almost to the summit and break out of the top of the fog into bight sunlight from the San Jouquin Valley. One of the wildest hours of driving in my 40 years behind the wheel...
