A brief note for people suffering from a sinus cold:
First, travel over Malad pass, I-15, in southern Idaho. Did so today and my right sinus, blocked all day, suddenly popped open due to the change in altitude.
Second, stop at the Chinese Gourmet restaurant at 4500 South and State Street. Eat some of General Tsao's chicken. It was spicy enough that it also caused that pesky right sinus to open. Done both in a day, I'm now feeling pretty good about things. Of course, that's an expensive and time-consuming way to treat a balky sinus, but it certainly does work.
