#1 smell- Gardenias. My Pawpaw had such a green thumb and would have the most beautiful Gardenia bushes. He would cut a bloom off to send home with me, by the time I drove the 20 miles home my car would smell so lovely. Everytime I smell a real (not the silly fragrance junk) gardenia I think of my Pawpaw.

I also like:
-Fresh cut grass (if I have allergy medicine)
-The smell before rain
-Fresh Roses (not the florist kind)
-My DH right after he showers.
-Spice Cake baking (especially my Mammaw's recipe)
-Mammaw's cornbread
