Is the wooded area a place that is yours? Or does the property you hunt/own stop at the creek? The reason I ask is if I were bow hunting the area, I would be finding me a nice tree at one of those bottle necks of woods and putting a stand there. The set up you are talking about sounds perfect for rifle hunting. I've always said, it's hard to bow hunt if you aren't in a tree. That's just my opinion, but for me it is. If I'm in one of my box blinds up high, I'm typically never close enough to the deer. If I'm in a ground blind,, same problem.
It also sounds to me like you are messing with the feeder too much. You need to leave it in one place and if you want to move it, do that next year for next season. Once you are established a place, the deer remember it- hence, the does smelling the ground (because it's NEW area than where the feeder was at before) and leaving. I built a box blind that sits on top of a home-made wooden stand and it's 6'x4' and it's 8' in the the air. I have it in the middle of a hayfield, that is considerably hilly. BUT, I put it in an area where I can see all directions at least 300 yds or more. My point is, I put that stand out early september and haven't been back sense. The deer have to get used to it. Depending on the location and situation, it may take deer a week to get used to something or it may take a month. Heck some deer may not notice something new at all.
Do I think you are hunting that area too much? NO. I don't believe that's possible unless you are hunting it morning and evening every single day,,, then I'd say, give it a rest and hunt somewhere else. From looking at your land, you don't have alot of cover or woods, but if you can access that wooded area for hunting, I would and especially during the rut. Now, I realize this is probably their bedroom or "sanctuary" but I would maybe use a climber and hunt the area lightly - probably would not go TOO deep in the woods.
