Occasionally.
On the trip to Nova Scotia this June, my wife and I camped near Peggy's Cove. Between the campground and the village is a memorial marker to the victims and responders of the downed [link|http://news.bbc.co.uk/onthisday/hi/dates/stories/september/3/newsid_2495000/2495403.stm|Swiss Air 111]. You may recall faulty wiring was to blame. Where one sat made no difference in this case.
While the memorial marker was not a destination per se, I took the opportunity to stop and see it.
Now that I'm retired and there is no business travel I'm always flying with my wife. While she's getting better, take-offs are a "white knuckle" time for her and I am generally holding her hand. One can't help but think of the "what ifs" at that time.
