Spring in Egypt

We're halfway through April and temperatures are rising to almost 80-degrees during the day. Many online friends are mentioning allergies. That's understandable if you live in the U.S. or Europe, full of spring flowers and budding trees. But my allergies are kicking in, too, and there isn't much here besides the desert. The only planted areas are farmers' fields, near irrigation canals from the Nile, or those places where property owners water plants and trees with water piped in from the Nile. The rest is just one big, dry desert (with an occasional stubborn camel).

So where are those evil pollen-meanies coming from? I'm pondering that question as I go out to buy more allergy medication...
