Brand new carpet, freshly sawn wood, leather stores, clean barns, dairy farms, freshly mown grass (although I am hightly alergic, so I don't go there), but my favorite odd smell is the smell of dust burning out of the furnace when it is turned on for the first time in the cold weather. I hate cold weather, but I love that smell. I think the wood smell would be a great Yankee Candle Scent, but I don't know about the rest of them, except they did have fresh cut grass for a while.
