Oh here is one for the historians and completists out there: a list of dates for skateboard competitions in 1991. Although I personally disliked all the competitive stuff, I was very keen on the idea of sharing information and pages like this seemed important to me. I think many other people thought they were a complete waste of space.
This was at a time when the notion of skateboarders and skateboard events within the Soviet Union seemed very novel and so I would have been particularly delighted to list those.
