lit? the dang thing darn near is impassible in winter, we only take it when there is no snow.......only roads that are lit around here are inside city limits and even then not always........that Highway 200 through Lincoln is going through wilderness areas......we use it as a "short cut" to go from Great Falls to Missoula in late spring/summer/early fall.....2 lane road, many miles between small towns, goes up and over the continental divide.....why would we light them? cost a fortune and not gain much.....
