Bird Park / Glory hole / Koppie

LOL. Must admit. the bird park is stinking and not romantic at all. I can think that nobody would suspect that u could meet sumone there...lol. So where is the mentioned GloryHole then? Definately not at this bird park...Any ideas of other possible dogging spots? The only one I know about is the one at the Sterpark koppie, but people tend to just drive past there...I think the cab light should be used by both people parked there but also by people just driving past slowly...my ideas are finished. Any better suggestions?
