On the way to Glacier National Park

8/30/12 We stayed at Placid Lake on state rt 83. Fortunately Peter spoke with the woman at the gas mini mart in Twin Bridges about the smoke-she told us that I90 east of Butte was closed & that was the route we planned to take! We took I15 to I 90 to state 83. Looking at the map, we wondered if gas would b available. Peter spoke to a couple of farmers in Avon & they told him it was available in Ovanda MT
