A few squares N/E of Farnborough are interesting due to the military stuff (including Bisley range) but mostly doable with a bit of planning.
The stuff in the NE of the square by Potters Bar/etc will only take one or two rides to pick off.
That'd take you to 36x36 with a bit more work required for 42x42.
