Amen on the working out, there is a huge difference in running around at under 1000 feet vs above 5000 feet. Get use to drinking a lot of water because it is mostly high desert in NM and you will get dehydrated in a hurry.

I have not hunted that unit so I can't help on that but your conditioning will help when the time comes. Just remember to pace yourself and keep extra batteries for your GPS, you may need them. It's not hard to get lost in the mountains. Depending on the weather it could be any where from T-shirt warm to snowing in the mountains so be prepared either way. Early Sept is more likely to be warm but you never know. Good luck on your hunt.

BTW, I'm hunting bulls and bucks in unit 15 this year.
