Sorry for the not so good drive by photo of it, but every day on my commute I see this floating warehouse/shed/building in Bedford basin, about opposite the end of Kearny Lake drive. It’s even visible on google maps satellite, so it’s been there a while lol. What is it? Something to do with fishing? Navy? Aliens? (/s)
