There were four workshops after the march and rally part, held at the Eucentre, which I'd never visited before. They were on shaming language, partner abuse, polyamory and masculinity. I led the one on polyamory, which was well-attended and well-received. I feel especially great because I feel I helped support this event. Not just by leading a workshop, either - I publicized it to Boston Cheap Thrills, on Fetlife, and in other places, and helped set up the workshop space.
gato_preto found a flickr stream of pictures from the event. So far I haven't seen any photos there that show me clearly but if I do find one I'll post it here. If you are interested in seeing more what the event was like, here's the link to the whole stream: http://www.flickr.com/photos/31167233@N08/sets/72157626545202061/
I'm not often very politically active. If I always had as much fun when I did it as I did on Saturday I think I'd do it a lot more frequently. :)
