EC - a very considerate response. I believe the problem lies in part by the idiots who dont talk/squak/listen etc as you so rightly said BUT there are problems with airspace acces that so many GA pilots have experienced. It is sad but true as we hear many times on these forums. As DSA is not going to be very busy we should see virtually no transits refused and if they are then they should be properly and officially questioned. This is not taking a stance before the event really no more than stating the obvious. I for one believe we have the best ATC in the world but there is the odd "trouble spot" for GA
