What is the essence of a skateboard? It seems that some people, for some reason, under the inspiration of some muse or other substance, asked this deep philosophical question. And, luckily or unluckily for us, they actually came up with the answer: two wheels. After all, one can't go anywhere with just a board and no wheels (unless it's a hoverboard). But can you really get around with just two? Apparently yes, but not without skill, learning, and perhaps a few bruises, as the Post Modern Skateboard demonstrates.
