Yes there are a few occupants BUT:

1) Private security is searching ALL bags, backpacks, duffles, etc and no plastic tarps, sleeping bags, etc are being allowed in

2) When in the park seated on a bench, one MUST remain in an elevated seated position. No leaning or prone resting is permitted.

3) No bottles, cans or food permitted.

4) They have a 3 ring binder full of security pix and they scan it when they are "assessing" the entrants acceptability. If you are in the book, No Entry Permitted.

The park is, after all, Private Property and the owner is establishing his rights/rules for entry.
