My son and I went to that game in a Honda Accord. I had been outside clearing our driveway and thought that the roads seemed fine. Thankfully we didn't encounter anything that seemed at all hazardous.I know this isn't what you are looking for, but I thought it deserved mention. February 6, 2010, 20 inches of snow fell on Pittsburgh. The game was not cancelled, but officials asked that people not come to the Seton Hall game at the Pete.
Only two of the 2 refs made it to the game. But myself and plenty of others still did. A crowd of 6,681 was announced which was silly because there were no tickets or turnstiles -- fans just walked right in. And the crowd was closer to half that anyway.
Nonetheless, inside the weather was wonderful and so was the game as the Hoopers won by 25.
To go further afield, I was in law school when Pitt closed the university during a bitter cold snap, after the Governor declared an "energy emergency." I bought a knit cap from the University Shop because my ears felt frostbitten, and my eyelashes froze walking to Ruskin Hall.
