Of course, that disclaimer made me pay much more attention than I would have otherwise. The table offered information about the bison in the park and about how they can be killed by ranchers if they wander outside the National Park boundaries. (There are no fences to keep the animals inside Yellowstone.) If I understand correctly, ranchers want to kill the bison b/c bison can carry a disease (brucellosis?) that, if transferred to cows, would cause the cows to have a stillborn calf. However, there's never been a proven case of the disease moving from bison to cattle, so the ranchers don't have much justification for their fear. Nevertheless, as the law stands now, ranchers can kill bison if the bison are on their private land. So this group was encouraging people to sign a petition to change the law and prevent ranchers from killing bison. Seems like a good idea to me.
