Would be really surprised if Sziget had both Travis and Post. Might work for the kind of crowd they draw at R&L but I doubt it would work at Sziget too well.
The audits are everywhere.
I quite enjoy DJ audits who goes round industrial estates and films with his drone and gets confronted, probably says a lot about me. 😄
He knows every aspect of public filming, which in turn runs rings around the police. Which is chucklesome and there incompetency.
