While the recently released, 90-minute Best of Slednecks DVD ($20) is sick and wrong in several ways, it?s also pretty damn entertaining, what with all the speed-metal music, heinous biffs, video game graphics, and no-frickin?-way-he-just-did-that gap jumps. But our guilty pleasure does have its limits?like when these barbaric motorheads start mucking up our big mountain lines. (And to our credit, we fast-forwarded through those segments, screaming ?Why? Why?? at the screen.) Should you buy this DVD, we recommend a matching donation of at least $20 to the Winter Wildlands Alliance to cleanse your karma.
