any particular reason it is known by the local constabulary? are you likely to get clamped or questioned? or has it got more of an 'adult' reputation?
Sorry I've only just managed to return to this thread. The hill is apparently known officially as Pine Tree Hill and, as someone else has remarked, I have never seen a pine tree, even a dead Christmas tree, there. The Police do Patrol it and certainly keep it under observation as they are trying to stop the idiots who hurtle around it at stupid speeds endangering the lives of those who just want to sit peacefully watching the comings and goings, not to mention causing a noise / fumes nuisance and tearing up what remains of the grass areas. I happen to know about the name becasue I was sitting there one evening using my radio (I have an Amateur Radio Licence) when a Police 4WD hove into view. They had come, amongs other things such as a security check, to try to catch the little perishers on bikes who had been making life a misery for the rest of us. Needless to say the little dears had vanished so they conducted a security check - all very polite, cheerful and good natured. I thought they wanted to speak to me because was using my radio but they hadn't even noticed it! Instead the two or three of us remaining all had official notices handed out to us to say why we had been asked if they could look in the car boot. I was apparently stopped and searched under the Prevention of Terrorism Act. As I said, there was nothing sinister or nasty about it and it has given my friends something to laugh about ever since. Parking and driving is now very restricted up there with an official notice marking the place you are not supposed to venture past in a vehicle.
Flightrider - thank you for the information
