The deer haven't been pressured yet. That's the whole thing. You can undo it in a single sit.
Entry matters more than the stand itself. Figure out where they're going to be between 4pm and when you show up. Walk in around them, not through them. If you bump them getting in, the sit's already over — you just don't know it yet.
Wind's obvious. But thermals aren't. Evening sits on a hillside: as the temperature drops, your scent drops with it. That perfect downwind position at 5pm is pushing into the drainage at 7:30. Know which direction the deer are coming from when that happens.
Get higher than you think you need to. 20 feet is the floor. Scent disperses. Movement is harder to catch. A deer that isn't looking up won't look up.
The one thing: don't burn your best setup on bad conditions. If the wind's wrong, don't sit it. You're not going to outsmart the wind. Save the stand for when it lines up — you'll get fewer sits and better ones.
That's early season. The window's tight. Don't blow it on impatience.
