They are both boardsports, and they both share the need for balance. So, what do surfing and skateboarding have in common?
Surfing and skateboarding both have decks, boards or planks. And they are fun to ride. One could be seen as a means of transportation; the other was also a Hawaiian past time.
They share many tricks, and maneuvers, but they also breathe the same cultural values and lifestyle. If you surf and skate, you live the same dream.
