I was delighted, in a way, to be able to walk along the roads (note the vantage point of the photo below).
The lessons here are two:
(1) It's a better idea to not rely on a personal automobile in very many cases, and this is one. The three who made it on time [myself included] relied only on their two feet and on the subway (to its credit, the subway ran normally, at least the Orange Line did-- however, all local buses were cancelled). The three who didn't make it all had cars involved in their commutes (all drive to, or are driven to, subway stations) to come downtown.
(2) Things are cancelled for a reason during inclement weather! (Look at what happened to J.F., as described above).
We couldn't do our afternoon practice teaching, because of the sixteen "practice students", only the Slovak and two Russians said they would come, an insufficient number. Being unaccustomed to snow, every last one of the many Latin people "threw in the towel" (as well as the Japanese woman). We went home early.
