"Now authorities are investigating how the Big Dig -- or, more precisely, a structure built for the project -- became something else: the site of an unauthorized indoor driving range for state troopers who love golf."
The chairman of the Massachusetts Turnpike Authority had never heard of the golf range until a local TV station did a story on it.
The state police started their own investigation this week after a reporter started asking questions.
The golf range is in one of seven buildings built to suck dirty air out of the tunnels -- similar to the one pictured here. The driving range takes advantage of a 25 foot ceiling. (Boston Globe)
