When we lived in St Albans, it was nothing to hear rockets and mortars going off in broad daylight - any time of year. Our dog was petrified, she'd try and dig a hole through the bookcase and into the wall to get away. The worst time was from early October through to mid January.
In darkest Shropshire all is quiet. Save when they're shooting pheasants and I'm getting showered in shot from some idiot shooting high and slightly my way. Got some apologies for that, which I never got with fireworks.
Present old dog is stone deaf (thankfully).
