Contexto:

Growing up in rural Vermont, there weren’t many places for Tom, Dave and Steve Mull to skate. The resourceful brothers often made due with what they found in the woods around them, letting their boards act as a medium between themselves and nature.
It’s this principle that their skate collective The Worble is built upon. Now residing in LA, the boys are just as likely to be found tearing it up at the Lincoln Park Skate Plaza as they are *jumping sludge* down in the LA River or working other natural elements into their daily sessions.

Pensé en "deporte aventura", pero quería algo más preciso. ¡Gracias!
