Looks like even more great info since I last posted. Thanks guys!

Well I wasn't feeling too hot this morning but I rode in anyway. The only thing that stunk was the ice-cold air in my lungs, I didn't like that at all. But beside that, I just took it easy and leisurely (sp?) rode on in. I don't feel any better or worse for it but while I was riding my sinuses seemed to clear up and I could breath, which was very nice.
