RE: dead deer question.....eh.
Couple years ago someone paoched a deer 10 yards in front of my stand. They took what meat they wanted and left the carcass. When I found it the yotes etc... cleaned it up pretty good and it smelled bad. In fact that is how I found it, I smelled it 15 yards before I saw it. I drug off what was left and 2 days later killed a 152" 8 point out of that stand. I don't drag off deer to gut them anymore. Last year we killed 3 deer out of the same 100 yard square area. Two are on the wall. Gutted them all where they dropped. Two were killed within 2 days of each other. I would remove the carcasses, wait two days, and hunt there, if conditions (wind etc..)are right.
