I realize this is a narrow-field request, but every morning around 5:30 – 6:00am, there is this horrible clanging noise somewhere coming from the east side of the block of Clinton between Sackett and Degraw. The best way I can describe it is that it sounds like a woodpecker drilling into something metal. It sounds like it’s coming from higher up, on a rooftop or something, but I can’t see anything for the life of me. Anybody else out there heard this noise, or any idea what it could be? Thanks.
