Pony, Montana is a tiny little town in southwest Montana. It is a former prosperous gold mining town which boasted nearly 5000 residents in the late 1800s. It is almost a ghost town today save for its 150 or so residents. Many fine homes and buildings sit abandoned as well as a ramshackle assortment of failed businesses in the center of town and less than spectacular housing on the edges that have been long abandoned.
Although I have seen it referenced as a 'ghost town', I really don't see it that way. There are some beautiful homes, a few thriving businesses and people call the town home. The ghost towns I have visited in Montana usually have less than 1 resident.
