Excellent commute home this afternoon at 37F and sunny with winds from the W @ 7mph. When I was coming through the town before mine, I noticed a car in my mirror that was holding behind for about 10-15 secs. I could also see that there were other vehicles behind it, so I pulled off to the side to wave them around. Little did I know there was a huge line behind that one car. There had to have been at least 25 vehicles that went by one right after the other. No idea where that traffic came from because not a minute earlier, there was no one around. As soon as it was somewhat clear, I pulled back out and continued on my way. It seemed 85% of that traffic all turned left at the stop light ahead, so I passed most of them as they were waiting to turn cuz I went straight through.
