Actually None!
We set them up with nitrogen tanks / regulators / hoses etc to run the air tools. The car was a retired Nascar car made street legal with the exception of exhaust (although I'm sure it wouldn't pass inspection). All camera's were hand held or car mounted. No permits, no notice, no permission.
Their biggest concern was that the driver could be ticketed and his Nascar license pulled......they wouldn't say who was driving.
Thanks to previous SBRT shenanigan’s we knew just what they needed to get the job done. :sifone:
