This is just a short post about a side-effect of terrorism, such as we have witnessed these last two days. I live in the Chicago area. I have a very dear, close friend who is a professional musician. He has a steady, Saturday gig at Sears Tower. Even though there is no real rationale for it, he feels a little spooked about being there now. I have to admit, I,too, am wondering, what if ...? That could be another ideal target, for some misguided fanatic. They closed Sears Tower, yesterday, along with most public and government buildings, museums, zoos, and many other places large crowds usually gather;like amusement parks, ballparks, stadiums etc., and of course the airports. Some are reopened today, but we are still effectively under siege, as it were. These are strange times to live in.
