I've talked with some people over the last few days about the crazy week in Boston/West, Texas and even here in town, and I've asked them whether or not they think this is one of "remember where I was" events. I can think of four days for sure in my lifetime (I'm not that old) where I remember where I was and what I was doing when I heard the news: the shootings at Columbine, 9/11, the shootings at Virginia Tech and the shootings at the Batman movie in Aurora, Colorado.
For people older than I, some of those types of events from the last 100 years might include Pearl Harbor, JFK's assassination, the Miracle on Ice or the Challenger explosion.
Any big ones that I missed? And what's your take?
