Why would they waste a ton of money on equipment and supplies that would be used once a year if that? Better to cancel school and to have make up days later on.
Knowing they weren’t prepared, I would have canceled school to. But when your main problem is ice it’s not hard to have city/county trucks that can also serve as salt or sand spreaders, for instance. We have them here. The same truck picks up my leaves in the fall, deposits sand/salt in the winter, picks up my brush in the spring and keeps up with general maintenance in the summer. Driving reminders are also important because sometimes going as slow as possible in snowy/icy conditions is not your best bet. Sometimes, if I don’t keep a steady 30-40mph highway the snow and ice tends to build up on the windshield, The extra speed helps blow it off and doesn’t substantially increase the chance of an accident, IMHO.
