Fast and flowing downhill through the forest. The steep ‘G Drop’ for which the trail is named can be bypassed by a new B-line to it’s right. (Note, its not actually a drop and can be rolled).

New B-Line added to bypass the final drop if required.

This is a waste of time. Basically a straight old forest access with no real turns until one left berm right at the bottom
