Did anybody put in an official protest?
I was very tempted.
As Neil says, I tried to approach from the east. On the map this looks the best way of getting around the rhodos. The problem was that the rhodos extended eastwards into the light green forest and there was no obvoius edge to them as suggested by the map. Once in the block of light green it was impossible to get to the control from the east. I spent all my wasted time to the east of the rhodos in the light green. There were various changes of vegetation in this area which it was possible to believe were the veg boundary on which the control was sited.
After eventually finding the control (on the third attack from the north) I was then able to leave it directly to the west, i.e. through what was marked as dark green on the map whereas the light green to the east of the control was impenetrable!
Some acknowledgement by the planner/controller of this issue would be appreciated.
