Power Steering Update

After a couple days a spot developed under the car. I know that its power steering fluid because its kinda red. I'm not sure why its leaking yet, but I snapped a picture from the area of the car directly above the spot.

I can't tell if its the high pressure or return line coming from the rack that has the leak. I also can't tell if the previous owner tried to bandage the leak with a rag? I don't think the rack itself is leaking however.
