The Gray wolf can live in a large range.  From the open prairies
 to forests.  Nowadays wolves in the wild can be found
 in: Canada, Alaska, Montana, Northern Minnesota,
 Wisconsin, Michigan, Washington, Idaho, Wyoming, and North
 and South Dakota.  Mexico may also
 have a few wild wolves as well
(www.californiawolfcenter.org).  The wolves that have been
 reintroduced into Northern Minnesota have received mixed
 feedback in acceptance by land owners.  The land owners
 that raise livestock are worried that the
 wolves will ruin their herds, however most of the
others are either indifferent or have
 a positive attitude with the wolf
 reintroduction (Attitudes of rural landowners
 toward wolves in northwestern Minnesota).
