Got an email on one of my building distribution lists that made me laugh:
So, it seems like we’re entering the Fireworks and Pop Rocket season (first episodes occurred last night for all you light sleepers). If your sleep or pets are disturbed by this activity over the next few weeks, it is imperative that you report every issue to the Seattle Police. The non-emergency number to report disturbances is (206) 625-5011. If the disturbances are urgent in nature (fire, injury, etc.), you need to dial 911.
For General Inquiries, contact the Seattle Police (East Precinct on Cap Hill) @ (206) 684-4300 (Option #3 for the Clerk). This was the guidance provided by Seattle Police.
