I think round here at least the new regulations have had some effect. The pub down the round had a display, and while they were still loud, they were nowhere near as loud as they were last year. Plus, they all stopped fairly early. Maybe shops have been more careful who they sell to this year, as I haven't been walking home past the usual gangs of school children letting off rockets in the afternoon. None of my bunnies seemed to care at all, but it was my birthday last month and I got Donkey Konga as a present, so they have had to learn to cope with my bongoing.
I'm sure some people will have saved up their's for tonight, but I think the worst is over now at least.
