I can see this from your side and theirs but all I can say is it is unethical but not much you can do....I hunted some land once and we made the lanes on the landlines on our side of the land and we got done the same way long story short we spent the money on the dozer to make them but we learned a valuable lesson ......never do lanes on the landlines again bad idea but we all was friends throughout the years and all went well just be careful and hope you the best and it isn't worth getting hurt or in trouble over deer hunting .
