There were people working behind Racer. They were either coring or drilling to set posts. If you don't know what that is, they were using a drilling rig to make holes. Sometimes these are to take core samples prior to construction, or to place concrete pilings. I was not able to see much, any ideas?
Of course building behind FOF and The Racer makes sense because of the room back there.
Also I was told that King Cobra has been sold and will be removed by December. This seems to fit with some sort of construction.
