JustMe seek & ye shall find, really, there will be some people there who you will be friends with, groups are often bad - you have to seek & destroy, take them as individual & get to know them.
I moved to DH's area before DS was born and it was cliques a-plenty. I threw myself into all of them & whilst I do not get on the with the 'groups' in general I have many individual friends, meet people & cherry-pick.
I live in a very middle class area, mainly couples but if you can penetrate as an individual you'll find people, interesting people, it can be very cliquey but my friends around here are dipsomaniacs, world recognised artists, writers, librarians, shop owners, journalists, child-minders, gardeners, farmers, film makers, Olympians, furniture makers, publicans, livery yard owners, teachers, florists, builders, electricians, equestrians, photographers, SAHMs, vets, furniture makers, illustrators, musicians...
They range in age from 20 to 85.
Just get in there & KEEP getting in there - you'll meet them eventually.
