Yesterday was a good day. Any day I can commute gas-free is a good day! In the morning the outside temperature was 18°F but the batteries were a toasty 70. Even with the cabin heater drawing power to keep the windshield clear the batteries were fine all the way to work. Ditto on the way home. I even drove my son to the high school later in the evening before plugging in.
Of course, between today and tomorrow we're slated to get almost 2 feet of snow. So I wimped out and drove the dino burner this morning. The CdV would probably be fine even with a 2 hour commute, but why risk it?
