Here are some pleasant natural fragrances that I enjoy. The fresh smell of water in the air right after a thunderstorm; a recently mowed lawn or hayfield. Salt sea air as the fog rolls in on a summer night. Spring time at home when the ceanothus or buck brush is blooming on the back hill. A spring time bike ride when the local flowers are blooming. The Tahoe and Sierra pine trees. The musty smell of my grandmothers cellar from long ago. Iowa farms as long as there are no cattle or hogs. Lastly, chocolate chip cookies baking in the oven, okay maybe that last one is not a "natural" fragrance.
