Your first job is to get to Fisherman's Wharf. Turn left out of the Motel, then do a right around the corner. Make a left when the street ends, the first left on this road. Hopefully you are now heading towards Telegraph Hill. The arrow is along the road just a little way short of it. Now turn around and burn it south. Once you finally reach the warehouses, locate the one you want and park up there. Take it nice and steady trying not to catch too much felony. The arrow is 1 block short of the very far South. This shouldn't pose too much of a threat to you as it is fairly easy to complete.
