RE: Where??
If you get 100 responses, you're gonna get 100 different answers, and 100 more posts criticizing everyone else's answers.
but i'll stick out my neck and give my two cents.
without scouting at all (which obviously i would), i would set up the camera either above the cross in the pic, where all 3 fields are the closest, looking for trails in there, or walk the fence and look for hairs on the barbed wire where the deer are going over or under the fence. in my experience, bucks prefer to jump over a lowspot in a fence than try to fit UNDER a highspot in the fence.
also, moving the camera around can be a good idea, or a bad one, see what works for you.
good luck.
looking forward to seeing your pics.
