I went with an outfit across the river from Mike a few years back (which was an extremely expensive nightmare). I will say that country has the right genetics/age structure to produce many book deer and if we had permission to hunt any ground larger than a postage stamp, it would have ended really well! Mike is the man in that country!
Edit: well damn I should have scrolled down! You are with the right guy! Being from the dakotas, you will know what to prepare for but, weather can get really arctic that time of year! Good luck!
