The Philly "Art of Living" meetup group is hosting a very popular yoga rave dance party and will be serving delicious vegetarian food at this event. If you're into yoga, meditation, or just having a really good time with like-minded vegetarian people, I think you will enjoy going to this event. For further details, please see their web site:
I know Hong-Mei Li, one of the organizers of this-- she is very kind, friendly and welcoming.
I'm not sure whether I'll be attending yet, but I wanted to announce it here for the benefit of those in our group who may be interested. Please follow RSVP instructions at the web site above, but also RSVP here so we know who all from our group is going.
