When we went to the Festival Fireworks last year, we were too far away and the battery on my remote trigger died.
This year, I put a new battery in before we left, but the battery door kept springing open. Had to get duck tape to hold it closed. Found a good spot at Castle Street, only to find the other part of the remote trigger had died!
The result is an accidental effect looking towards people with a much better viewpoint. The rest are blurred from the button push.
There’s always next year.
