250 people (my graduating class was 249, plus there were others involved in the ceremony). I didn't particularly care but I'm sure there are others out there who might be less thrilled to know that there is now video out there of themselves that they didn't approve of.
What I thought was interesting was my bff's comment when I sent her the link. She told me I actually look younger now than I did 38 years ago. I think part of that has to do with the amount of makeup I was wearing in the graduation video, plus my short hair (I haven't worn my hair that short since college) and, of course, the fancy cap and gown I was sporting. Though I do consider myself to be aging fairly well...or at least not horribly <g>.
