You are so right in your overview of these events.
Speaking only of the NCCA events, we have found that the Technical Roadshows have been a bit better than OK as far as response is concerned. The Factory Tours and Workshops have had superb responses.
The AGM is a bit of a different animal. We need to plan roughly half a day for the AGM, that leaves half a day for the attractions and networking. This is very limiting.
A few years ago, the AGM was held at Carpex. The show attracted more members and others than we could have coped with, but being an all day event, the AGM attendance was appauling

So as you can all see, an AGM is a very difficult event to organise and balance well.
Me and Pawlo (NCCA's CEO) had a recent brainstorming session and Pawlo came up with what I think is a great idea for a themed event to accompany the AGM. We'll thrash it out at the next Board Meeting and let you know afterwards what's happening.
Safe and happy cleaning
