I see Calif is really cracking down on the vaccination issue. Especially in LA county:
Customers must present proof of vaccination to enter indoor businesses in Los Angeles starting Nov. 4 under an ordinance approved by the City Council.

It includes outdoor events with 5000 or more attendees. I don't think BFI has that many people, and I'm not sure how they could verify it if there was. But the fact they have began enforcing such rules may deter some people from attending all events for now.
This has become an issue with other major events elsewhere as well. The SEMA show in early November will be heavily hampered by the current regulations in Nevada. As a result the number of registered attendees is way down this year. Some events (like AAPEX, the sister show to SEMA) are even requiring more stringent rules than the law requires as a precaution. That has further dampened their response this year.
Although there are some early signs that the Delta variant is beginning to plateau, it isn't over. Even worse, there has been yet another new mutant strain of the virus beginning to surface. I believe this is the sixth or seventh variant of it and so far it appears to be much worse than the preceding ones. People that should be immune (either from surviving a previous Covid illness or having been fully vaccinated) are not. Sadly the vaccines were developed before any of the mutant strains existed and are proving to be much less effective than hoped. Therefore that may not be the answer, we may have to go back to strict lockdowns until this thing burns itself out.
What does all of that mean for events like BFI? Hopefully people will protect themselves and practice proper protocols to prevent contamination and we can continue to enjoy them.
