If you're planning to visit Custer, Montana, you need to know whether the town is on a reservation. Although the town is not a reservation, many people have reservations about visiting this historic area. To avoid the trouble, you can visit Custer State Park, which is home to almost 1,500 North American bison. These creatures can grow up to be six feet tall and weigh as much as two thousand pounds. You can also find other types of wildlife such as antelope, mountain goats, bighorn sheep, and burros. There are also bobcats and mountain lions in the area, which are generally very nocturnal and not particularly friendly to humans. When you visit Custer, make sure to keep your distance and stay out of their way.
