Hi Roob,
I fly at CGC and to be honest most members are either around retirement or their late teens to twenties. I don't think you would have a problem socially, I'm the odd one out as I fall halfway between, not many of my age but that doesn't really worry me as I am mainly there to fly. They are having a fireworks party on Saturday, that would be a good time to see if you fit in socially. I'm sure non members would be welcome if they knew you were as prospective candidate so to speak, 6 quid a ticket...
