Willow place car park in the town center. Go to the top floor of the car park and go to the fire exit/ stair case. There is always a motor bike next to it so it's easy to spot. Cameras don't work and no one goes there. I've been there a few times and always get action.
Just past Grafton Underwood, (on the way to Brigstock) on the right hand side is a layby leading into Grafton Woods. Perfect place to get naked in the woods with no-one around, especially in the afternoon!
Just out of desborough along the arthingworth road is a spot where doggers have started to go, they part up on the estate in desborough and walk over the bridge, which is the a14, turn left and along the track. Been a number of dogging events down there.
Google earth / maps show you what it is like before all the trees were estabilished, really good long deserted track along the unlit side of the a14, close to kettering, rothwell and market harborough
there is a secluded grassed area between the council offices and the leisure centre. I have had action during the day but mostly in the morning. Park close to the access from 7 am and see who parks next to you and take a stroll
Could be good dogging site , Bears lane leads to Fermine woods loads of places for fun public footpaths all around there are some dog walkers about but nice and quiet . Directions go into Weldon turn towards Oundle on A427 leave Weldon at top of hill left hand bend turn right onto Bears lane follow road to end of track fermine woods in front .
