HAPPY HOLIDAY WEEKEND: Now, let's be safe and legal!
Ignition or discharge of fireworks within unincorporated Kittitas County is only legal ON JULY 4th, from 9 am to midnight. Private fireworks are not permitted on Federal or State lands.
We urge you to stay safe by exercising common sense and good judgement. Serious accidents and fires do happen with fireworks; don't be that guy, or that neighbor, and have a happy Fourth!
