You have got to love Phantom FIREWORKS. They have a great page full of links to state by state regulations of our favorite pastime.
Just find your state and click. If your state doesn't ban FIREWORKS, then send your Governor a nice postcard thanking them for keeping FIREWORKS legal.
If they do ban them...then send your Governor a huge bag of STEER MANURE! Then burn them in effigy!
