Betulaceae, Thy Art my Cryptonite.

Today the Pollen count hit the ceiling. Every year this happens, and every year I am just as surprised to find myself floored around the time the weather turns warm.

I've often said that there are two weeks of good weather in Chicago every year - one as hot summer turns to cold winter, and another when cold winter turns to hot summer. 

I was wrong. As it turns out, there is one week of good weather in Chicago each year.
