Kirk,

I did. One day by myself at the Hobbs Standard Class Nats last month I
located two thermals by sight--a refinery burning off gas in a large
flame and, later, a dust devil. I used my olfactory sense to help core
them both...in my ASW 24 (albeit with the nose vent wide open!).

The refinery thermal smell was more powerful but the dust devil-
spawned thermal had a distinct "agricultural" odor, too. They were
both narrow and fairly strong and I needed all the help I could get
staying centered. I flew in and out of the refinery thermal several
times before I finally got it cored.
