Well, NYC is considered the "Big" Apple.
Not to mention proliferating generalized anxiety across the nation. In many cases it is enough for them to inhibit our ability to function normally and enjoy ourselves.
Thanks a lot you guys. My 21 year old daughter is in Times Square (well, in a hotel across the street) with a bunch of friends from college. This was our pre-graduation-from-college-with-HONORS gift to her. Something she has ALWAYS dreamed about. Yes, we were very concerned for her safety but she had a point that if we let the terrorists intimidate us into drastic changes of lifestyle...well, they win anyway.
STILL, I have the bone weary concern of a father who knows the world is far more unforgiving and deadly than starry eyed idealism and youthful enthusiasm can comprehend.
