I have lots of stand sites and don't decide which I'm gong to hunt until shortly before I go out in the morning after reviewing the wind directions for the day on the weather radio.
Too, there's always the possibility that something might come up that would prevent one from getting back out in the morning. I wouldn't worry as much about the elements as I would, mice, squirrels, porkies and other critters chewing on the bow.
Of course, theft is always a concern. Folks who steal stuff don't care about entering private land either.
I do sometimes leave a set of outer clothes in a plastic bag. Luckily, I have more than one set. It's sometimes been as much as 3-4 days before I get back to the stand where I left the clothes because of unfavorable wind directions. So far, nothing's chewed on my clothes, but I don't do it often.
