In reply to Geras:
It can be a good way to be sociable though, + have fun in / outdoors, which aside from the exercise, is hopefully going to make yr black dog more wuffy + tail waggy, phaps becoming an adorable golden retriever or spwingy spaniel, or just a happier black dog.
Sometimes people can be cliquey at these places, and unsociable too, which can be depressing. Or you might find it hard to be sociable when faced with lots of people having fun + being sociable. Sometimes it just doesn't make sense what's going on in your own head...
Bouldering + being antisocial can be fun too.. just being focused on doing the stuff, but also try getting in the way of cliquey groups stuff, that's going to be fun in a way too.
Also, bouldering outdoors on a week day with no-one else around can be great too.
I don't do much bouldering at the mo, but these are my thoughts.
