If you're in a neighborhood, I think it's pretty shitty to shoot them off past 11. Does it bother me personally? Not really, but I'd never do it. We have several different folks very close to our house that spend enough on fireworks to take a week long Disney or Yellowstone vacation. I can't do it. Not sure I could spend more than $30 on fireworks and look myself in the mirror the next day. I will say all the folks near us wrap it up pretty early. I don't think I heard any past 9:30 or so last night.
My dad used to say, your burning money. First time in my life we bought some and shot them last night. Shot before 10pm. Stuff is expensive. I worked for an importer in Florence growing up and would get pretty much anything I wanted free on the 4th. Brother and I shot huge volumes of stuff. Never paid for anything.
