wyoming leftover tags

[deerslyr]

Im looking into buying a doe antelope left over tag in wyoming this year. I will be living in billings so Im looking for a unit thats close to there. Im looking at units 15 or 16 but now I just need help deciding which unit. 16 seems to be the better unit with more antelope and more walk in hunt areas but 15 is closer. Would it be worth driving the extra distance to 16 to have better opportunities or will it not really make a difference since ill be hunting for does?
