It makes no difference if it is on public or private land, you will need to buy a non resident license.OTC bulls are about $600 ,cows are cheaper.I don't have brochure handy ,so can't quote exact figures.You will also have to buy a $10 Habitat Stamp,unless you are over 64. ( might be a break for active military)
Some private land licenses are good only for that piece of private land,some are good for the entire game management unit.

You will have to get the big game brochure to see what unit you will be hunting and see if an OTC tag is available there,was it all in a draw, or is it a Private Land only tag. There is also a $1 surcharge per license for public hunter education and Search/ Rescue.
You will also need a Hunter Education Certification Card unless you were born before 1945 or under 18. Check that to make sure I have the numbers correct.
