We went to the local fireworks display last night. Very nice fireworks. To me, though, these organised firework displays quickly get boring and repetitive. A minute would be enough, but this lasted for about 20 - 25 minutes!
The ultimate firework display for me will forever be what I saw during my childhood: A lot of people in our local community were involved in shipping, so had access to caches of distress signal flares intended for sailors in trouble at sea. I suppose these had an expiry date, so would have to be replaced after a while. These rockets would fly particularly high before they released a para-shoot that enabled them to float in the sky for several minutes, emitting a bright red or sometimes orange light. On New Years Eve the sky would be filled with these!
