 Coming to the line, and you're racing. After a year away, the head of the Charles was back for three days of races in mid-October, known as the largest regatta in the world. The race spans three miles of the Charles River, starting at Boston University's DeWolf Boat House and finishing just after the Elliott Bridge. With more than 11,000 rowers, some say there is nothing quite like this. As we were going down the course, we sort of like, I looked up after one of the bridges and just seeing like a line of like so many people. It's just, yeah, it makes it fun. Spectators cheered from both sides of the Charles and peered over bridges to get a glimpse of the races live. Some have been attending for years. At this year, the vectors and the rowers and the teams and people, it's just the line. With up to 300,000 spectators attending, race organizers say this year's event is estimated to generate more than $3 million for the state of Massachusetts. Reporting from the 2021 head of the Charles, I'm Sheena Neary-Arty for BUTV10.
