Exciting field trip Open Thread

I won’t be blogging until this afternoon, because I am going on a very exciting field trip with one of my children.  I’ll tell you about it later — assuming, of course, that it is as exciting as it promises to be.  If I’m bored out of my mind, you won’t hear a thing from me.  Oh, and just to keep my excitement going, tomorrow I’m having lunch with an old friend who has spent his career in the military.  I can’t wait to hear his stories.
