If you mean -in person- then there is quite likely an autism social society in your area, they probably have a web presence, cuz otherwise we would never find them. So search up words like that and see if you get any results nearby.

The club and social activities will generally be oriented more towards the more profoundly affected members, but it’s common that the volunteers working with them will also be autistic but able to handle organisation and responsibility of the other members. So whichever you are looking for, you’ll find them there.
