I agree with cohntr6. end of october is too early for "rutting" in most of the rockies, even up north. you will see younger bucks with does, but gennerally speaking, the larger, mature bucks will not be seen among the does until after the first week of november, and even then it dont really heat up until the mid to later Nov. There always are exeptions, but as a rule you can expect the mature bucks to be solitary right now, an maybe with another smaller buck. This time of year, I almost never see two big bucks together, it's always alone, or with a much younger buck. . .
Again, this is just what's "normal" or averge for me to see. I know there are guys that will say, "I saw three monster bucks together with nine does, on October 24 once. . ." but that's not the norm. I'd be glassing those nice little, quite, out of the way pockets, and watching over the rest of them. Dont get fixated on watching the main herd and then forget to look in those off the path places where the bucks hide!
