Y2K was lots of fun. I built special software for Lufthansa, upgraded their servers and spent some very enjoyable time in Frankfurt am Main in Germany.
For the "main event", I was sitting next to my wife at the San Diego Sheriff's Office dispatch. It was an odd way to spend New Year's Eve together. It was mostly a nothing burger. The remediation that needed to happen was done in time.
I was in the field at that time as well. It's kind of maddening to hear people talk about y2k like it was just an overblown scare scenario when the reality is that it was people like you me and thousands of others that did the work that saved the day.
