I will be honest, I have never dogged before , my question is this How does one introduce themselves at local spots, for example I drove to one this evening, I thought I spotted somebody wanting action, but could not be sure, There lots a empty park cars, just outside a county hotel, near to where I live, i saw a person sat in their car with music on, they started their engine, once I got out my car, but I got no other sign, So was insure and maybe a little scared to approach the car... Is there any clear or special signals or inducation thathe other person is into Dogging ???
