That's the thread for it, but I'll fill you in on a brief summary of it!: it's a trick night on the rooftop of a multi-storey car park next to Old Spitalfield Market for people to practice and learn fixed gear tricks and the likes. Plenty of drinking, chatting, listening to music and the likes happens as well. It's a really fun night. It was great for me especially as I am new to both fixed gear and London.
