Tuesday morning greetings!  The weather that DR Cillaliz talked about last night and DR JRand talked about this morning is headed to SW Ohio today.  The only problem I had on my way to work was fog, but we're supposed to have snow for the evening commute.
TOD - one of the worst traffic back-ups I've ever been in was on I-75, going to Cincinnati.  We were stopped for a very long time and when they were about to reopen the highway an officer came along on foot to warn us that the pavement might still be a little slippery.  I asked if a tanker had overturned, spilling oil, and he said, "Tanker, yes.  Oil, no.  Mrs. Butterworth's syrup."
In the 10+ years I've worked in downtown Dayton, I've experimented with all possible routes between home and work.  The most obvious is I-75, but I've found that taking the old road (US 25) is just as efficient.  Getting to the interstate from our house adds miles, which was an issue during the time I was leasing cars, and most of the major traffic jams occur on the highway, not on the surface streets.
