You must go to Three Forks, Montana. The headwaters of the Missouri is there, which is terrific and important. The Missouri is the longest river in North America and it begins in a truly nondescript spot.
Not surprisingly, there is more than one reason to go to Three Forks, population approximately 2000. Another is Jim Phillips’ Horn House, visitors by appointment. Jim currently has 16,171 antlers. And at least as many stories. Words fail me here. This is something you just have to see for yourself.
