On my friend's backyard box I started doing what would be I guess a semi daffy grind. Basically anybody could prob do what I did, but it was like a small tailpress on one ski(basically the toe piece of my binding was just off the edge of the box) and a small nosepress on my other ski, the heelpiece being just off the side of the box. They are pretty fun. Ill see if I can go further than that on my backyard box. Ill post some footage once I can get out there after my broken toe heels.
