There are several areas of class D in the country that have me scratching my head as to why they are there but there they are and we have to work around it. I would have thought that the best thing to do surely would be find somewhere else to fly from? I know the convenience of a full ATC field with instrument approaches, lighting etc is nice but if you are getting riled with the situation there then I would move. I don't know the GA scene at that end of the country but there must be somewhere close by.
What about Thurrock or Damyn's Hall?
I currently fly from four different airfields so it's doable.
