He better not take the advice to shoot his antelope up in the Mayoworth area, as that is way up in unit 20. Unit 21 where he has a tag is southwest of Kaycee and not even close to where you mentioned. I would concur that the area is good for his Y deer tag, but the roads you mentioned are all over on the east side of the unit where it is 95% or more private land compared to further west of there quite a ways where the BLM land is that he needs to hunt.
