Yep. Before I got into technology, I was a lighting designer, and still dabble on and off. Producing a safe, quality, decent-sized event is hard and it is even harder to do so profitably. Every now and again someone asks me to be part of organising something, and my answer is always "no, thanks for asking, and please rethink your plans". I have seen too many experienced organisers fail at this - even when you do everything right, things can still go badly.
