Re: combo whitetail predator hunt
Start by getting the "150" whitetail out of your vocabulary..It's not a good thing to base a trip on. While most outfitters with ample property have these kind of deer roaming on their leases, none of them are going to tell you "Sure, you'll get a shot at one". 120-130 would be more realistic, and if you see a 150, all the better, just don't count on it..
As for the predator part of it, I see numerous coyotes every time I go out to either Wyoming or Montana...I even see them sitting along field roads and such, but it's all up to you and your partner how much you want to intrude into the whitetail hunt..We catch coyotes out all day long, not just a nighttime proposition.Bobcats are often in the mix as well.
Prices....For what you are interested in, probably figure that you would be going as a "spotter", so you wouldn't expect to pay for a full deer hunt, I'd say 4K total for the lad and maybe 1K for yourself.
