POTUS has said 1917 about 20 times in the last few days.
I think Flynn would have the same career description.
There is a good decode on yt showing how part of central park is called 'wonderland', lexington & concord are intersecting roads near central park. There is even a 5:5 on one of these roads.
The CF is there and there are abandoned tunnels that run right through all of these, right to pier 90.
