You do not have to ‘occupy’.
Without being disrespectful, just stand in front of the wire,shoulder to shoulder, forming a continuous human chain completely around the space with two or three key openings. Possibly then allowing only vets and citizens, and discourage the Press or Politicians from entering.
As an aside, people can be standing by to take the place of those who become tired or need a bathroom break. The chain may require a few thousand people, but out of 300 million plus, there should not be a problem getting volunteers.
Getting there in sufficient numbers is going to be logistically difficult...
I’m still looking to hitch a ride at the very least...
I don’t need much, just fresh water and someone to let me out to go to the bathroom...;-)
