If a public course is closed by permit, I think that part should be emphasized. The first thing the interloper will say is, "You can't close the course! It's a public park!"
If you can respond, "It's like a block party.You can get a permit to shut down the block. We got a permit to shut down traffic on this course for the day."
They will still be annoyed that they drove to a course that is closed, but it usually stops the "I have a right to be here!" argument.
