Bonfire Night....

Now seems to be called Fireworks night. As a child I always remember it being Bonfire night - bonfire toffee etc..I have been looking at the various fireworks taking place around the SE to decide where to go with the family this weekend and I think we will probably head to Blackheath (although given the funding cuts there will probably only be one whizz bang). But why is it so hard to find a bonfire - I think the nearest is in Crystal Palace.
I assume it is due to health and safety, woe betide I guess anyone who wants to burn a guy fawkes....
