The first picture looked cold, but was beautiful, but it reminds me of, well, here. The lake lays at the bottom of my street, in fact I've never lived more than a couple of tenths of a mile from the lake in my town - three miles of it is in the United States, the other 30 are in Canada. Plenty of ice fising here.
Plenty of vehicles thru the ice every year. Like Mike said, people either rushing the season or procrastinate - ice house often go thru too. People here are quite foolish. Ive seen open water one day, then a light freeze over night and people on the "ice" the next morning.
You need to to where the currents run until you have plenty of cold nights because the ice is thin over those areas for a bit longer.
Plenty of people love it.
Glad you had fun Mike.
