The 42nd anniversary of San Francisco Pride happened this weekend. People from all over the world filled the city to celebrate. It was too large and fabulous for words, so I can only personally comment about fursuiting at some street parties. There was no organized furry event or mission, just a good opportunity to wear a costume.
The last organized furry participation was a float in the 2005 Pride parade, arranged via BAF and its mailing list. (I heard that there was some negligible drama about connecting furries + LGBT, but it stayed internal, with positive reactions elsewhere.) Due to logistics and cost, it hasn't reoccurred.
However, one of the organizers posted on Facebook: "The SF Pride committee bugs me every year to bring the Furries back, and that's just what I am going to do for 2013! That's right, for the 2013 pride parade there will be a Furry float!" (Yay!)
