Interesting observation.
There are far more skateboards around than two years ago - and fewer rollerblades. Skateboards come in many shapes and sizes - but usually the scruffier the better. You can tell a really cool skateboarder, because his is well worn and often just a very dusty looking grey. The least cool are colourful and new. We saw a silver, embossed skateboard, but it was in the Museum of Contemporary Art and unphotographable.
