I would definitely take the stand down. I am not sure I would leave a note or not. In Ohio, you have to have written permission from the landowner to hunt on his/her property, so they would be breaking the law in my home state. I have been asked by the landowner where I hunt to run anyone off the property that I come across. I had that problem for a short period early in Oct., but they did not put up a stand. If they had, as I said earlier, I would have taken it down
