Movie popcorn (though I don't really enjoy eating it)
Fresh coffee (though I don't drink it and never really have)
The smell of fresh earth after a field has been plowed under in the fall
The smell of the first somewhat warm spring morning, usually about 2 days after the last snow has melted
The smell of burning propane from a sunflower heater in an icehouse
We used to have a sugar beat processing plant across the river from us. The thing created some God awful odors, but there was one from a certain stage that I actually enjoyed, it brings back some nostalgic memories.
The exhaust from an outdoor motor
The smell of the inside of a Plano tackle box that has been in the sun for a while
Wood smoke
Fresh cut pine
