Fair Way

      The Westborough High School golf team had taken the official photos with the state prize. The other

teams, disappointed, were on the bus heading home. And then Westborough instructor Greg Rota noticed

something wrong on one of the score cards. A 9 had been recorded as A 7. They were not the state prize

winner; Woburn High had won. "No one would have known," said Woburn's instructor, Bob Doran. For

Rota, it wasn't a difficult decision:"The prize wasn't ours to take."

Coin Stars

     "College students are lazy, but they also want to help," says University of Pennsylvania graduate Dana

Hork. So she made it easy, placing cups in rooms where students could leave their spare coins, and handing

out cups to first-year students to keep in their homes. Her "Change for Change" effort has collected $40,000

for charities, which were decided upon by students.

Never Forgotten

     A school in Massachusetts received a $9.5 million check from Jacques LeBermuth. But it took officials

several days of digging to discover his connection to the school. Records showed the LeBermuth came from

Belgium and studied in the school in the 1920s. When his family fell on hard times, he was offered free room

and board. LeBermuth became a trader, owned shares of AT&T and lived off the earnings until he died, at

age 89.
