Devium - Dying Days from Devium on Vimeo.
A group of guys go to a good deal of trouble to skate inside a big concrete pipe at Shasta Dam. Reminds me of when me and my buds swam to the base of Mansfield Dam at Lake Travis. Just being there at the base of a large dam is an unsettling experience, and then these guys go way back in the tunnel. Some people like caving. Me, I've never cared for it.
