I scouted the area south of the power line pretty thoroughly, and I just told you the best spot. North of the power line, I'd love to set up right off of that field corner in that pinch point (41.364069, -92.999353). It would be a good approach from the lake, but I'm not willing to walk that far. This piece isn't hunted hard at all... tho they may come in from the private lands west of there. If you go, you'd need to find the right tree and cut some shooting lanes ASAP.
The other is right outside of Ottumwa:
41.045386, -92.375444
The only place to park is right along the entrance ramp for the highway. I work right by here and wanted to find a spot i could go to right after work. I was planning on hanging a stand here until I found a farmer who gave me access. Nobody hunts this area, and there's a lot of deer. I had to call around just to make sure I could hunt it... but I know for a fact that you can!
With this, you'll have to let me know how you do!
