I find getting bucks on trail cameras sometime is as hard as hunting them I have had strange luck as well with cameras. In the spring, if I put out salt for the cameras and if it is near where bucks travel I'll either get nothing or an entire bachelor group. I also found bucks are always moving differently then I expect. For example I had 95 pictures on a camera that was on a trail to a seep and in just a week with only spiker bucks and does. I bought a better camera and noticed there were a lot of pictures with no deer in them then I realized there was something deeper in the woods paralleling the trail. So I moved the camera for a closer look (so it was facing away from the trail) and voila there were the big boys walking parallel to the main trail (but on the upwind side....I think they were going to a different place because if you ask TR they are usually on downwind side to smell the trail). Then in another instance I put a camera in a wide-open place where a ATV trail met a field and 5 bucks were crossing over the ATV trail like clockwork because it was some kind of funnel for them to go from slough to woods. That was total luck on my part. When I put cameras on rub route they are usually vacant until certain times of the year.

I think once I nail down how to get bucks on camera consistantly I will be able to arrow them consistantly lol.
