Most people who live in or near Washington, D.C., avoid humidity whenever possible, knowing that in time it will find them. After all, the District was built on a swamp, and it  has the miasmic air to prove it. 

This usually appears in the summer, however. Winters tend to be bright, dry and clear. They’re the only time when you might actually seek a steamy environment. 

Which is what we did yesterday, strolling through the tropical plant display in the U.S. Botanical Gardens. There were banana trees, palm fronds, poinsettias in their (semi) natural state. There was air so thick you practically had to push it aside, a heavy curtain on a breezeless August afternoon. 

On frigid winter days, the place is  a welcome antidote, but yesterday it was 60 degrees outside and the tropics were … a  little too close for comfort.
