Can anyone tell me which airports in New Jersey are good for plane-

I was in the Home Depot parking lot adjacent to Linden Airport when
local police told me I couldn't be there, since it was a "restricted
area." There's never any point in reasoning with the local police, so
I left.

any help would be appreciated.

I would ask them very nicely whhere you could look up that law that says
that.
