dogging in the Hayes, Middlesexwest London areas

I pretty new to all this and I've decided to try something that I haven't done before (and this would be at all) and since I've attended my first party I've decided to give this a go and I'm wondering if there are any dogging spots in my local area or nearby that I can get to.

Just to give anyone a better clue as to where I am I an near the M4 motorway but I'm closer to the Hayes bypass (but I'm not going to say how close I am)
