The rancher filling the water bag kind of got me. The plates say" Montana 1949, his coupe is about 1937, rather old for a road trip even then, and the boys riding in the trunk,, with a trunk, guess it was doable then. The shop pic with the Ford T, obiously colorized, the white tires would have disappeared before WWI, and the car is an early 20s, hope the hook on the chain hoist was hefty enough.
