I'm for amalgamate but don't want to loose the level of service I get now. Would be happy with a staged membership. Currently local CG has three stages, PWC, boats to 50 km and boats to 100 km. I'd be happy to pay an extra amount to be a member of another group where I holiday BUT at a lower cost than a full membership.
In my mind, if there's no reciprocals or staged membership for multiple locations there is little point in amalgamation.
