 In Cape Elizabeth, the school board voted to send a major school system overhaul plan to the November ballot. At a public forum last week, the board explained that the new middle school could cost more than $73 million. And two weeks after winning the NBA championship, the Boston Celtics are up for sale. The current ownership group bought the team back in 2002 for $360 million. In a statement, the Celtics say they're selling the team for estate and family planning considerations.
