I already have one, two, three active blogs in addition to this one, and it's a daily struggle not to start more. One idea that I've so far resisted would be a dump archive of web videos featuring the sounds of riding -- the single most important choice made by an editor in my opinion.
The soundtrack-less "718trailer," embedded below, would be filed under "very well done."
As seen on the Holeshot blog (and a lot of other places, too). DVD available at Dan's.
Of course, I'd like to add that bmx is cute. did it three years ago (to less impressive effect).
