Well, the terrain and the trees are going to block the police car's radar until you get relatively close to the police car. The big question is whether the officer is using constant-on radar or whether he decides to use instant-on radar. Constant-on radar is no problem since any decent Beltronics, Escort, Whistler or Valentine radar detector will detect constant-on radar will in advance. On the other hand, the officer may decide to trigger his radar gun only when he either hears or sees your approaching car. In this case, no radar detector is going to save you -- unless by chance there is another vehicle located not too far ahead of you (considering the trees, less than 1/4 to 1/2 of a mile away, or maybe even less) which gets targeted by the officer first.
