A Hurricane Grind is where you do a 180 into a Fakie Feeble. So go find a rail, parking block, etc., and try this. First, 180 so you're above the rail and only land on the back truck so you're doing a Fakie feeble. Your front truck has to go over the rail and be on the other side while grinding. Keep most the weight on the back foot and a little on the front to keep it in the feeble position. This trick is all sick looking. If you want to see one look in Transworld Magazine, they usually have them. Now try a 180 into a Fakie Smith.
Good Luck!
