Thanks, everyone. I think there is some good advice on here. I learned a couple of things. I think my suggestions are fairly obvious, but I think some people overlook them, especially newbies.

1) When you scout where you're going to hunt: As other people have said: hunt the wind...when you can. I do it whenever possible, but I mainly hunt in the mountains, so winds can and do often change during the day or swirl, especially in saddles, which can be great places to hunt. So it's good to take precautions. I am fanatic about keeping myself and my hunting clothes and equipment scent-free. I don't use carbon-activated scent-blocker camo, but...

I wash everything in UV-free and scent-free laundry detergent. And, before I wash my actual hunting clothes in the washer, which still has perfumed residue from the regular detergent, I wash the clothes I wear in the car or in the cabin on hunting day with scent-free and UV-free detergent to wash out the residue and reduce the amount of perfumed scent that rubs off on my body before I put on my hunting clothes. I wash myself in scent-free soap and use scent-free deodorant. I use Scent Killer and it works really well, I've had deer (very wild deer at that) walk right under my tree and the downwind from me the same path I walked in on, but they didn't scent me because I used Scent Kilelr spray lavishly on each laye rof cothing I put on, as well as my equipment and my gloves before I walked to my stand, all over myself and my equipment after I set up and sprayed it over my walk-in trail for 20 yards from the stand and beneath my stand.

That said, try to pick multiple stand locations for multiple wind directions so you can be ready no matter which way the wind blows. I see LOTS of deer, relative to other people wiht much more hunting experience who hunt the same area I hunt, and, as far as I know, I have only been scented once in the past 3 seasons I have hunted, using this approach (Note that I don't claim to know about all of the deer who got near my stand, but, as far as I know...)

2) Pick out specific trees/blind locations when you scout in pre-season (and in-season), look up at the tree/blind location from where you think deer will most likely give you a shot at them (i.e., along the main trail, etc.). Look at it from about their height and the height of their vital area, so you can see things from their angle. This will help you (a) see if you will be silouetted or other give-aways you might not otherwise notice and (b) so you can see any stray branches that might interfere with your shot and either cut them away before the day of the hunt (so you don't make a bunch of noise and spread your scent any further than you have to doing it the day of the hunt ) or be aware of the non-obvious branches you can't cut away, so they don't ruin your shot. This approach also will make you more aware of your most potentially productive shooting lanes and may make you change your mind about stand locations. Once you've found a site, mark it with a reflective pin or similar reflective material so you can find it in the dark.

3) I always wear a facemask. I think it breaks up my human profile and keeps bugs off.

4) When a deer comes into range, I usually squint, as I think that makes my eyes less noticable, especially if I move them to keep track of multiple deer. I also think it makes any necessary head movement less obvious than having two big white balls moving around.
