My friend got drawn for bison, so we are heading up to high level/rainbow lake this weekend. I was just wondering if anyone had any tips on how to judge a good bison bull? With deer one uses the ears etc to judge, but with bison we aren't sure how to judge a really good bull. We have been looking at a lot of pictures online, so we have an idea of what a good bull will look like, but I'm sure someone knows some tricks to get a more accurate score on a bull before one shoots. Thanks in advance for any tips
