I lost it the night of the Temple Burn sitting on an art car next to a couple of people who had taken or were going to take mushrooms. I think the girl was trying to talk the guy into taking them. Anyway, when the burn was over they hopped off and probably grabbed the sweatshirt by accident. The art car's home was 9:00 and Esplanade. It looked like a bar (there, that should narrow it down!). I went by the next morning to look but they hadn't found it either.
The sweatshirt has a small hole in the middle and a faded spot nearby. It's old and scruffy, but very sentimental--it's been with me since my first Burn back in 1996. Awwwwwwww!
