Congrats on the tag. I am not familier with 42, or what you hope to get out of the hunt. But if you are just going to enjoy the hunt and don't care about getting a record book animal, I would go unguided. Then take the $2,500 or so that you would spend on a guided antelope hunt and put it towards another hunt for your daughter. I don't believe you need a guide to hunt antelope, especially in WY. There are a ton of goats around there. I went unguided on my first antelope hunt in WY and scored on the first morning. I'm going again this year and taking my wife on her first antelope hunt. Pull a camper or rent a hotel, and you'll save a bunch of money.
Just my .02 Good luck.
