Well, I did wear the armband to Fenway. Many thanks to my wife, without whom this would not actually have happened.
Somewhat the worse for wear at the end of the day, but you get the idea.
There was a long line for blood donations, so I was there for about two hours. No one said a word to me about it. But I'm guessing some people did notice it, and thought about it.
I heard a chunk of Tom Ashbrook's On Point today, which was a show on Islam in America. It included a good discussion on the diversity of opinions and beliefs among muslims in the US and around the world.
