There is a reason a lot of schools, especially older schools, don't have air conditioning. They are usually empty in the summer, and by the time classes start the weather has started to cool off.
That hasn't been happening this week. Summer seems to have saved its hottest, nastiest conditions for the last week in August, at a time when many schools are trying to get classes started. Several schools in the area have sent students home early, and curtailed athletic activities because of the excessive heat, in the classrooms and out.
It seems to be an annual debate in Minnesota, whether schools should start classes before or after Labor Day. We have said in the past that the decision should not be left up to the state's lake resort owners who want to squeeze in that last day of vacation.
But maybe we should listen to the weatherman, at least until all schools have air conditioning.
