Starts today, ends next monday. You know the deal. Well, actually, you probably don't. Read the rules! This time around, no footage without a date mark will be accepted, even if only one person submits a video. If it's obvious that your tricks are old or reused footage, it won't count. Read the Original post with the contest description here, and the rules (important!) here.
UPDATE: You can now do up to 2 tricks in a park, so long as they are both in a different park.
