I don't wholly blame the 'management' at MSCC for this apparent mess, organising something like this takes time and effort, and there seems to be a lack of willing volunteers to help do it "in house" so the obvious solution is to farm it out to a professional organisation ... unfortunately they will want to make a decent profit, and that's where the rot sets in.
Yes, MSCC could have spent more time understanding what the vast majority of members wanted from the anniversary, but I think most of the centres will have their own events and this should have been the culmination of the celebrations. Just a gathering and a dinner would have worked for me, but - hey - that's me being critical rather than constructive and offering to help!
I'll likely get the £25 concours exhibitors pass (and turn up in the Volvo).
