Your question is too vague. What's important to you?

Is it the culture of being totally present, here and now? Well, then you need to find something that without cell phones, computers, etc.

Is it the culture of sharing? Then you should find something that tries to run itself without money.

Is it the art and the spectacle? Find your local arts community. That's probably the easiest.

Find something doing stuff you like to do, go in and participate--even if you are an introvert. There is something very different about standing on the stage than standing behind or beside it.
