Here in the semi-rural area where I live outside of Dallas, you can buy and shoot off most fireworks. The amount of banging and booming that goes on around here on the 4th (and New Years) is pretty impressive. Some folks nearby shoot off some stuff that's near-professional quality. The reports can be almost unbelievably loud and heavy. My old Army dad, who served in an arty unit, tells me that its not quite field artillery caliber, but it's related.
About 30 years or so ago, Texas outlawed bottle rockets of four ounces or less. Those were my favorite - we would buy them by the gross, go to a lake, and shoot them into the water, which gave a very satisfying whump
and underwater light show in the darkness. Also, my cousins had fun shooting them at each other.
