You know the alleyway with all those garages with the helicopter pad on top that you can buy? (Can't remember it's name) It's down the street from the stadium where you can do blood ring or that stunt thing with the dirtbike. From there go away from the garages heading away from the stadium. Go to the dirbike track that's on the beach about three or four blocks down. Ok, this is where it might be a little hard to follow. You know those buildings that are all linked together by jumps that you can drive off of from one to the next with a streetbike? I've flown over it with my chopper and can't find any way to lower the emergency stairways that you need to drive a streetbike up at the start (next to the dirtbike track) and at the finish of the linked buildings. (tallest one that has a very long steep stairway on the side that has a flat spot in the stairs halfway down) I know this is probably very hard to follow (it's very hard to describe) but if you know what I'm talking about can you tell me how to put them down or when they go down in case it has to do with a mission or something. Can you help me?
