Fireworks

Where I reside, fireworks are only allowed to be discharged within city limits on July 4th from 9 a.m. to midnight. Why then do people start setting them off in June?! Here are the laws in Washington regarding fireworks. To quote an old song, "Why don't we just call the whole thing off?"  http://apps.leg.wa.gov/wac/default.aspx?cite=212-17

I signed: "Ban Consumer Fireworks in Bellingham, Washington"
