Mack Dawg “Double Decade” Snowboard DVD: If we were traditional, we’d give Mack Dawg Productions a new china set for their 20th anniversary. But hey, this isn’t about tradition. Mack Dawg has covered 5 continents, hundreds of riders, and 25 films in their first twenty years. For a non-traditional celebration it was go-big or go home -- which is where “Double Decade” picks up. This mack daddy of Mack Dawg’s features an all-star crew and was filmed all over the world to find the sickest shredding areas. 20th anniversary blowout celebration? That’s what “Double Decade” is all about.
