Just came back from a trip to East Troy to get some good gas (more on why in a while). Headed down about 9:30, it was raining (I suspect freezing rain because the thermometer on the dash said 32 degrees), but I was about the only driver to take that into account, as everybody was blowing by at the speed limit, even with a car in the ditch just past Muskego. Then, about 9:45-9:50, a bit east of Mukuwanago, it started thunder-sleeting. People finally started to slow down.
On the way back, it was alternating between thunder-sleeting and thundersnowing. Most of the people finally got the message, as traffic slowed to 40 mph and most people had their lights on. Saw a car backwards on the other side of I-43. Stopped off at Wild Birds Unlimited to stock up on some birdseed, and took the back roads back home. More idiots without lights on, even as visibility was reduced to 2 blocks. Finally rolled back home about 11:30, and things seem to have stopped, for now.
If you’re driving out there, stay safe, and turn on your lights. If you don’t, don’t blame the guy behind you when he rear-ends you.
