We were having dinner with some friends, when we heard what sounded like firecrackers. Next morning, on the front lawn there was evidence that this had indeed been the case - see image.
I have happy memories of "cracker night" when young. We were living in a new part of the city, with unmade roads and vacant blocks of land. It was traditional for the whole street to build a bonfire on one of the vacant blocks and to get together at dusk to light it and let off fireworks.
