We found some archive video from West Kirby when I first put the production board record into the 40kt club. The wind was howling and when you see 66 knots pop onto the screen you’ll know why this has to be the windiest speed event ever. If only we kn[e]w then what we know now, maybe Yellow Pages would have never made it to the water, and I’m sure some of the guys would have been quicker with less crashes on modern free ride equipment.
