 Arizona News, ready to go. Fireworks on the 4th of July. Lots of shows being put on by the professionals. As far as the amateurs, some fireworks are legal through July 6th, but only from outlets that sell what you can light. When you see the tents around the city, they have their legal placard up there saying that these are legal fireworks. You go into your grocery stores, your Fry's, your Safeway.
