The History Channel (Channel 58 on Lowell cable TV) is showing a new documentary, Martin Luther King Jr Day: The Making of a Dream" on Monday at 8 a.m. and 2 p.m. If you're off from work on Monday because of the holiday, you and your kids should check out this show. The History Channel's website (follow the link above) has a large amount of information suitable for students of all ages. If your child (or you) think that history is boring, check it out. No one is second guessing the decision to cancel school yesterday. The temperature of minus-14 degrees with a strong wind would certainly have resulted in cold weather injuries. And since the schools were going to be closed for three days anyway, the fourth day off might cut down on heating costs even more.
