That's one of the most absolutely stunning videos I've ever seen. Whoever produced that work is an ace.
They did an awesome job. As an Eastie resident with a drone, I'm envious that they were able to get permission to use it there ("No Drone Zone"/FAA restrictions). But as an Eastie resident who also regularly enjoys Piers Park and the Harborwalk, I'm glad there aren't a bunch of them buzzing around.
It goes without saying that this is an incredible project. I like that they're trying to restore a more natural appearance to the waterline though I worry that it'll become a trap for floating plastic/garbage. But that's a minor concern and this will be transformative.
