Depends on what you are hunting with. If you are hunting with a compound and have to stand to shoot, probably need to brush it in some and put some sort of material around the stand to conceal as much of your body as possible. If you are shooting a CB and can simply sit and shoot off the rail, I'd still use a skirt of some sort, but as long as the deer have gotten used to it being there, and you don't move erratically then you will probably be fine.
All my ladder stands stay in the woods. I change the ratchet straps and support straps pretty regularly. They all have burlap wrap, which gets changed as needed. The deer are used to them. That being said, the ones that are in the open and don't have a lot of concealment, do not get hunted during bow season. Of course i hardly hunt my private spots during bow.
