Don't forget that BCRA used to have its AGM at HE but has now decided to make this a separate event.
The BCA AGM is rather a different sort of a meeting anyway because, at the moment, it is a place where things can be discussed at some length, rather than somewhere to formally agree points which have been discussed at length beforehand. That's not to say that it may need not to work differently in the future - it's just how it works now.
BCA is a HUGE improvement on NCA, which was held to ransom on a number of occasions by a regional council threatening to walk out and thus render the meeting inquorate! We've stopped that game but have a fair way to go before the organisation is really efficient - probably because cavers aren't inherently very "efficient" people at working in groups. The idea of rotating the AGM around the regions and having a "Party Weekend" with caving, entertainment, stomp, food, etc. all on site was a good one. Sadly, the northern cavers don't seem to want to go to the south for a caving weekend and the southern cavers don't all want to go north - so the views expressed at AGMs can almost oscillate between extremes.
Most of the regional councils work well because they are all involved in the same or very similar problems at a local level. There are possible solutions as to how to extend this to a national level and part of it, I am sure, is the idea of working groups to deal with particular issues - though we do have this already with a mix of Standing Committees and Working Groups. What BCA should not be doing is dealing with local issues - that's for the local cavers to sort out for themselves in line with how their region normally operates - and don't forget that access issues can be totally different across the regions and need to be dealt with in different ways. It cannot be "one size fits all".
I'm sure everyone involved in "running" BCA would love it to be more efficient and representative - but no-one seems to agree on how best to get to this position. I guess we just have to keep on trying to get it right and refining how BCA works - but remember that good will is all and nothing can be done if you don't have this good will.
