Fwiw it looks like Epstein either has a hand in the island immediately next to his, or at the very least coordinates construction with them.
2 more flag poles popped up the same morning a few weeks back, one on the North point of Little St. James (epstein's island) and one on the South point of Great St. James, on either side of "Saint James Cut"
These things are massive, was not one guy with a shovel.
