We returned from St. Marys a couple of weeks ago and have a suggestion for travel between Browning and St. Matys. We made the mistake of taking US89 from Browning to St. Marys. It was narrow, no shoulders, and very curvy and up and down. Returning home we went north on US89 towards Babb and then took MT464 east and south to Browning. It was a much better drive and about 16 miles longer. Was worth it to me. Some people talk about using Starr School Road between Browning and US89 but in my opinion it doesn't avoid the worst of US89.
