In case anyone is interested......
Mind the bad quality of the scan, this chart has been creased left right and centre.
Basically, the green diagonal centre is uncontrolled below 2500 feet and so it not a problem. The red circle in the top left is basically a no go area as it is for military use.
The pinkish area to the right hand of the image is controlled (above 1500 feet) but it shouldn't be an issue to get in here.
The unhighlighted parts are controlled and a little more difficult to get 'muck around scenic' access into.
As you can see, most of the 'interesting' area falls inside my green highlighted area which makes things simple
Cheers
