I didn't know PandaGuy very well but he was one of the first furries I had met when I joined the fandom back in 2003. I hope I still have the pictures from MFM back then, I won't ever forget the group trip to the zoo he'd help organize to see the panda on loan from China (nor him getting into his own panda suit in that horribly hot and humid weather and bringing smiles to the crowd of kids who had come to see a panda in a cage and also got the chance to see one a bit more close up :) ). I also had the pleasure of attending one of the last PandaGuy Picnics, I don't think those pictures survived my hard drive crashing back in 2005 sadly :/
But cheers to you PandaGuy, the fandom has lost someone special.
