You will be hunting much more beautiful country that you are used to, but if a 160 buck does not excite you, not sure you will be very excited in 70. I hunted 4th season a few years ago with a cow tag and my resident friend had a buck tag. Not much snow and I hunted around the base of lone cone for an elk. Didn't see any deer over 150. My friend hunted low where the does were and saw one deer over that during a week of hunting, but no shot. IF you get early snow then I think you will do well, but if warmer and dry, not so much. I do think you should explore private because by 3rd season, they pretty much stay there until the snow drives them down. Good luck.
