Buy several cheap treestands and set them up ahead of time,then hunt the ones when the wind is right. Deer do notice changes in their environment. Portable treestands are ok as long as the wind is right, if you get busted don't use that tree again. I like to hang 3 stands a month in advance, even then on opening day I was reading a book in my stand, quietely. Got that feeling I was being watched looked up and a doe was staring at me, Busted! Moved that stand the same day. Ive never hunted a tent blind for deer. This past season I turkey hunted and put out my decoys sat down 15yds away. Five deer walked into my decoy spred and hung around for ten minutes! No scent lok, no shower no problem. Next day I hunted from my tent blind and every deer stopped and stared at the blind from @50yds away
