Where is Marge? YSS Fun at WLA 2017

Marge Loch-Wouters, in her own words, October 19, 2017:

So this happened.  I was the YSS "secret game" at WLA17.  People got a picture of me and had to take a pix of me and the mini-me to win a prize.  And I thought my 772 students were just excited to see the prof!!
