Headed to St. Mary. A couple of routes show driving 212 and 2. Are these good alternate routes or would it be best to stay on I-90? Thanks for your opinion.
We go to Great Falls all the time from southern Indiana and usually take Mt 3 out of Billings to US12 then west to North Mt3/191 to Eddies Corner and on west on Mt 200/US 87 to GF. We have also gone across Mt200 from Circle to GF. In fact we headed that way in OCT. Happy trails.
