I hunt ridges, and the wind can be tricky at times. Best thing to do, IMO,is scout, find some good deer sign/trails and see what the wind is like at the times you plan to hunt with various predominant wind directions. Where I hunt, the wind is generally uphill in the morning and downhill in the evening, unless the wind is fairly strong (>8 or 10 mph), which may change that. Personally, I like hunting in a tree just below the top of a ridge near a deer trail intersection. This elevates me above the deer coming up from below, out of their smelling range and usually provides a good view of the valley/ravine and any trails that run along the ridgetops (which they often do in steep terrain situations, in my experience.

What TeeJay said is good advice, too, in my experience. Saddles, where the tops of two or three ridges come togethr is usually a good crossing point for deer from one valley to the next and tends to get a lot of traffic. The only drawback to saddles, in my experience, is that winds tend to be even trickier around saddles because of the possibility of winds coming up or going down more than one valley.

Good luck!
