I'd agree about the cycling clubs being different, we have 2 here and they are very different...
One loves carbon flashy new kit stuff, has a codebook with rules, always ride specific routes that never change, and call each other buddy and all that type stuff
The other one, is chaotic, disorganised, does not give a monkeys about kit, finishes rides at the pub, and is held together with
string and sellatape, and was called a bunch of complete amateurs. by the one above.
They do tend to appeal to different people, and the best thing to do is join more than one
