They've been touring around the Bitterroot Valley this week and the lineup of old Chevrolet cars makes people stop and smile.

The National Four-Cylinder Chevrolet tour (with vehicles built between 1912 and 1928) have been to various states and national parks over the years. This summer, they arrived in Montana and have been roaming around the Bitterroot Valley.

The drivers have been taking their autos everywhere from Missoula to the West Fork, with stops at the Lee Metcalf National Wildlife Refuge and St. Mary's Mission. The Daly Mansion is scheduled for Thursday.

The parking lot at St Mary's Mission in Stevensville was full Wednesday, June 28. (Steve Fullerton, Townsquare Media)
