jtj, I agree with azbobk; I too am bald, and what didn't fall out I shaved off. I don't have my Xfire roadster yet but I have the top down on my Sebring convertible as soon as the temp hits 65 and the sun is out; there is no upper limit. I admit in New England, the highest I have encountered is about 102 or so (top down). Maybe if I was in your part of the world I would change my mind.
