Great dogging place near Watford M1 junction 5. Come off motorway and take a41 towards Edgware/harrow. At roundabout with Toby Carvery go left on Radlette road and after about a mile turn left into High Cross, this is sign posted on the right of the turning. Drive past a few houses and you come to a white gate on right, seen a couple here mostly every Friday and Saturday night at it, also if you go past the white gate further down take the next left it is a closed road gated off by Thames Water, again action there after 8/9pm most weekends - only couples I've seen though
