Oooh, I like the dancing ladies' face powder idea!
Also wild rose, violets, crisp green prairie grasses. I suppose it depends where in the wild west we are! Now my brain is unlocking! And sarsaparilla, a tea with a licorice/root beer sort of flavor.
Have asked another BNer, Al Gae for some ideas. Don't know if he'll have time to post but he's working on some scents of his own using the American West as inspiration. If there's something we're not thinking of, he will!
