I think they shouldn't be on sale for residential stuff
I think organised displays should have to send information well in advance to local residents
The issue with designated times of year for particular things - I can see July 4th missing from the list plus I don't know what would happen about general parties, weddings etc. I think it would be much more manageable if it was official events only, places that have space. In London they frequently set off car alarms, it's ridiculous. Also so many issues with kids chucking them around.
