Stalker parents? Our son had an hour long (bumpy) drive, on busy streets, to get to where he had to do some snow clearing, of course we had to make sure he was OK! He did say that he saw one accident, everyone was fine, and he wasn't involved.
Our furnace quite working again last night, luckily it was only -12℃.
All fixed now, with more modifications and parts replaced (it doesn't like the cold and breaks down every year - even though it is only 5 years old - not made for our climate!). -30℃ temperatures forecasted.
