Yeah, I'm from Raleigh. It took me over 3 hours to drive home that day, on what was normally a 20-minute route. Bah, I wish I could explain how it happened, I'm still not sure. It really was ridiculous, we've had much worse winter weather (specifically thinking of the big ice storm from a few years ago) and gotten through alright.
Honestly, I don't think the lack of equipment was the big problem, though it certainly didn't help. Part of it was nobody was expecting more than a dusting of snow. When NC forecasters predict snow, we usually end up a getting a fraction of what they predict, if any at all, and it usually doesn't stick nearly as well as this powder did. So the salt/sand machine people were caught off-guard, and didn't have time to get out on the roads before a bunch of people tried to leave work early. I guess the people who left early must've been trying to beat the snow home or something, because the traffic problems started early, and I'm guessing they were caused by reckless driving. Combine that w/ driving melting the snow and having it rapidly re-freeze into ice, lack of experienced winter drivers, and you have trouble.
Even w/ all that, it still doesn't explain how pretty much every single major street going into Raleigh got jammed.
