Thrasher has a few Slave boards to give out but they want you to put some work in to get it. They want you to go out with your bros and film your best gnarliest Boneless and send it in via YouTube, Vimeo or Quicktime and good ‘ol Mumford will pick the top entries.

There will be a sweet montage with all the top entries once the contest comes to an end.

Deadline is June 6th at midnight.
