1. this trick is just a nosemanual grind.
2. ride up parallel to the object you are gonna grind on.Have your feet in the same spot for an ollie but your front foot just a little farther up. (you have to ollie and land with your front foot on the nose and then, if you're good enoguh, balance it out like a nosemanual)
3. ollie and center you weight over the nose as if you were doing a nosemanual.
4. to get off you have to do a little nollie so you don't hit your back truck. that would just be donk.
