Yea I think you are over thinking this way to much. Come on man 45 days? Nothing to worry about. I guess I look at it this way too, most of my real buck hunting is done during the pre rut when the bucks are cruising all day long. When they have does on there mind they wont think twice about smelling a human at "this" spot during the summer. And the bucks that are there now might not be the ones that are there in three months. If you hung the stand and planned on hunting it tomorrow then yea you might have something to worry about, but i think you will be just fine.
