pennington flash and other sites

Been onto the carpark on Pennington flash a few times now and only seems to be boy racers about. We normally go around 10pm and have gone on midweek and weekends.Does anyone know if this is a popular dogging site? We have also tried rivington and entwistle with the same results. The best place we have tried is Scorton but its a bit of a drive away. Could anyone help us with best places to go. We are still new to dogging so any help is much appreciated.
