New Jersey Statutes Title 5. Amusements, Public Exhibitions and Meetings 5 § 3-17

A portable booth may be used in places of public assemblage by churches, schools, and commercial, fraternal, civic or social organizations where by reason of the temporary nature of the entertainment, it is deemed impracticable to install a permanent booth. No portable booth, however, shall be used or permitted where entertainments last over three nights in succession.
