My DS16 will start school the 30th with a half day that Friday for Labor Day weekend. DH, a HS teacher, has teacher days the 25th and 26th. As someone mentioned earlier, schools in New England don't have ac, so the warmer days -- either at the end of the school year the third week in June, or the early fall -- can be lost to learning. It's just too hot to sit in classrooms and think.
