Go down the ramp that you are on. When you see the
two smaller ramps in front of you, do some light air tricks (No
Footer and No Hander recommended to get speed). Turn right after
the last small ramp then jump and grind on the left rail near
the barrels. Grind it until you are at the top of the ramp, then
jump and grind on that rail. Jump and either grind on the side
of the building (which is more difficult) or jump onto the building
and go straight at the curving beam and the far right end of the
building. Jump and grind on the beam until you get across it.
Then, turn right and jump and plant on that beam. Grind on the
beam until you get to the end and do a Back Flip to get the Secret
Cover.
