Sydney Fireworks go ahead petitions to stop them, on grounds of insensitivity. In my mind I keep hearing "Nero fiddling, while Rome burns".

When I lived in NZ, bonfire night was their summer and sporadic fires from rockets falling on tinder-dry grassland and creating pockets of fire that the fire brigade had to deal with. Professional firework displays would never have that problem would they? Hmmmm, the word hubris is now rattling round my cranium (bumping into insensitivity)

The UK has had some pretty bad fires on the moors in recent years. California?

A pattern is emerging.
