Wow, it was so long ago, almost thirty years, I really don't have a "defining" moment. It was more like I could so I did. Funny thing, the potential need for it was, at least in my opinion, really not there back then. And, I'll admit that there have been periods when I just didn't even though I could. Today, I actually, think there is a demonstrable need. So, there's my story, short and boring as it is.
