Myfathertook his wild free ranging WY bison monday morning, quite an old bruiser, was in a bachelor group of 6-8 males, pretty certain he was the biggest certainly top 2. May go B&C, so that'll be pretty awesome if he qualifies, having to look into all the details of what goes into that, but ya, quite an animal.
Getting a shoulder mount, that should be pretty awesome too when it arrives.
If I recall correctly, almost 18" long horns, bases I forget if they were 16" or 18" but around that range I think.
