Sun-dried laundry is a close second.
(I am not connected to any of the listings)
Honeysuckle from the bush in our backyard, the smell of my grandmother -- soft lavender, Thanksgiving dinner cooking, Mr. Hartman's pipe tobacco, Jean Nate bath splash and Chantilly Lace perfume and Irish Spring soap (my dad) and Dove soap (my aunt) and Old Spice cologne, spring rain and freshly cut grass, Comet cleaner and Pine Sol. . .oh and the bar shaving soap or Barbasol shaving cream. . .
What a fun and sweet topic. . .Now I am feeling wistful
Also, I enjoy the smell of a campfire and all the memories it holds of camping with family and friends growing up.
