Snow tubes were always my downhill vessel of choice as a kid, but maybe that’s because I never got to know the coolness of products like the Avaluge Sled. Says szlea: “Popular Science in its January 2007 issue noted that this sled ‘zooms down hills at up to 60 mph. Only the runners’ stainless-steel inlays touch the ground, reducing friction and increasing speed.’” Moving that crazy-fast, the Avaluge somewhat recalls Clark Griswold’s makeshift sled National Lampoon’s Christmas Vacation - only it’s about a million times slicker.
