I have given up flying into race meetings. People walking along the strip on final approach, taking off at dusk after an evening meeting and having another aircraft trying to land on the same heading, vehicles parked on the strip and finally a wet and long grass take off which added about another 30% or so to the t/o run on what was a very short runway and it should have been closed before arrival. I agree with other posters on here, it needs to be policed better
