These tricks are too much fun
to do. You just need a good ollie to get to the top of the ledge and land the back tracks of the skateboard down while the front tracks remain up. It’s called a 5-0 grind. You can tell if the tricks you do are front side or back side by going to the ledge here in the pic to the tricks I did are front side 5-0 grind.
Nice one!
