Some copter excitement coming to Beacon Hill tomorrow

It's no dinosaur delivery, but a helicopter is scheduled to bring a new generator to the McCormack State Office Building sometime between 7 a.m. and 6 p.m. on Saturday.

To be on the safe side, that means Beacon Street will be shut between Joy and Bowdoin streets between 7 a.m. and 5 p.m. and parking will be banned on Bowdoin Street.

Also, the fourth and fifth floors of the State House will be shut, according to a memo sent to State House workers by state building officials.

In the event of rain or wind, they'll do it in Sunday.
