Well I can tell you the the temperature in Chicago was NOT Many degrees, and certainly NOT enough.
As we were preparing to land I told my wife I was not thinking when I arranged this trip to pick up the new pup. We should have come up a few days earlier to stay and explore downtown Chicago since my wife had never been there. Then we landed and discovered what 15 degrees really feels like.
I will NEVER go back there in the winter. Fortunately I only exited the airport terminal for about 5 minutes to take possession of the pup.
My wife has warm fur coats that she misses wearing, but even she is no longer tolerant of such cold.
