Yes, there is a fireworks ordinance
Most residents of City of Polson do not know there is a fireworks ordinance. There is.
Among the salient points: Fireworks may be discharged within the city limits only on private property of the owner, or with the owner's permission, or on paved city streets which are not arterial streets or collectors when such discharge is in a safe and sane manner. Fireworks in the city limits are restricted to the July 4 holiday only: between 12 p.m. (noon) July 3 and 12 a.m. July 4; between 12 p.m. July 4 and 1 a.m. July 5; and between 12 p.m. July 5 and 12 a.m. July 6; and for the New Year's Day holiday only from 11 p.m. Dec. 31 until 1 a.m. Jan. 1.
Last year fireworks were shot from June 22 through end of July. It’s not right for people's sleep nor our wildlife and many pets of all sizes go crazy and suffer trauma during extended unlawful use.
