We left Iowa early this morning so as to get to Philadelphia in time for a conference. The driving was pretty eery. For the first several hours at least we were basically alone on the wide interstates. That might have been a bit eery by itself, but to add to the effect, there were lots of remains from people having been there. Dozens of cars, vans, and tractor-trailers littered the ditches. Some were right-side up; many were on their sides or upside down. Some were in reasonably good shape; others were well-crumpled. In one place about a third of a truck was lying on its side in the median. I don’t know where the rest of it was. All of the vehicles were deserted, since they were all victims of previous snowstorms. By the time we got there, it was sunny and the roads were perfectly clear. But it sure looked like an abandoned, wintry warzone. Not exactly the sort of image that normally occurs to one when one thinks of Christmas. Then again, maybe it’s good to be reminded that not everyone is happily celebrating Christmas with their families.
