You're right, that is an Osprey nest. They can't remove it due to Ospreys being an endangered species. Still works, the 12 port side isn't audible.
They put spikes on their new 2T22 at the main FD to prevent this from happening.
I just wanna tell you that this map has helped me so much over the last year or two. Hats off, Bijay.
Also, I'll be recording Boyce's Darley for the Saturday test next weekend. I'll post the video here when it's up.
