To be fair, when I went to Wyoming hunting antelope several years ago I was in your shoes. I had looked at maps, statistics, etc. but had never been within 500 miles of the place I would be hunting.
I don't know where unit 10A is, but the best advice I can give you is don't be afraid to ask for permission. I think that is the downfall of so many hunters, especially with some of the latest legislative talk, too afraid to knock on a door.
My experience hunting antelope in ND, even last year when the posted land debate was hot and heavy and I was right in the heart of the country that was supposedly in lock down mode, was that every door I knocked on had a very pleasant landowner on the other side. I think I talked to 5 different landowners. I was politely told "no" by one and politely said, "thank you for your time" in return. The others all told me good luck and told me where all of the roads where on their property and where the antelope were hanging out.
Don't be afraid to ask. Don't be afraid to knock. Don't be afraid to get turned down either. There's nothing so bad about that.
Good luck to you both. I hope she tags a big one.
