My state has legal sales on certain fireworks. The legal ones are supposedly weaker than the high powered kind and they can't go but so far up. My guess is that most of the ones I have heard in the neighborhood in the past are not legal. I was surprised to only hear some for about 30 minutes late Wednesday night and then none yesterday! I'm not sure why. It didn't bother me. We saw plenty of beautiful ones on tv last night in DC and NYC.
