I used to hunt next door to 23, never seemed to run out of goats.

"Layered" is the key to clothing, as you're apparently already aware. You will be required to wear orange (you can check the WY G&F website for specifics). Mornings mid-October can be "brisk", but what makes you comfortable then will roast you by 10:00. I'm not sure what weight of Thinsulate are in my Danners, but they're a good compromise to carrying a pair of cold-weather boots for the morning and lightweight hikers for mid-day. I would assume that yours would be fine provided you break them in properly if you haven't already.

Wind is definitely something a lot of people don't consider. Might seem simple, but having Chap-stik and sunscreen can help offset its tendency to dry exposed skin out. But, I've rarely found the ambient temperature low enough the second week of October to really concern me about wind chill. You'll still find temps in the 60s, possibly even 70s during the day. And, it can be very bright - so sunglasses might be useful.

Goats see very well. They're very used to vehicles in most cases, so the "pickup" comment above - while humorous - isn't far off. They'll pick up bipedal movement in an instant, regardless of your wearing blue jeans or camo. I've done well spotting them with good binos, predicting where they might go (whether they're browsing or whether they might take flight from other hunters), and setting myself up somewhere along their likelyroute.

Not the hardest critters to find, but the distances involved, their sight, and their speed make them a fun hunt. Good luck!
