My experience too is that "clubs" are not clubs at all but schools and hire companies for their aircraft.
Would it not be true that if all newly qualified PPL's, and indeed less recently qualified PPL's, were to push the owners of flying clubs to extend their clubs to indeed become clubs, a few owners may actually try to provide more group activities?
If nobody ever bothers to ask, an owner can not necessarily predict that demand.
The thought also occurs to me that we are all so busy rushing around in our busy lives, that we no longer seem to be able to justify spending that extra hour in the clubroom talking to others.... and I'm as guilty as the next on that score.
