That is what I recall. I said it did not freeze until 5 or 6 p.m., which was sundown. There was snow but not a lot of ice. I don't know about the main roads. I was walking around on the side roads. I did not try to drive after 2 p.m. > I think the first few hours of delay were due to volume, then once all > those people became jammed on the highways, it all turned to a sheet of ice. I guess so, but the total volume of traffic on the highway should not have been more than any other rush hour. Granted, offices let out between 4 and 6 usually, and they all let out at around 1 or 2 p.m. You would think there would be a queue on local roads waiting to get onto the highway, but not much delay after that. However, Terry observed people going slower than necessary on the highway, before there was widespread freezing. That would explain it. - Jed
