The piece de resistance?

I have exactly one week before eight Riverdale (my high school) students and two teachers (one former teacher of mine) arrive in Kunming. I am calling this the piece de resistance because since last summer this was the main focus of my China plan. While working for Minds Abroad, I pitched a Riverdale trip to China. After only a handful of meetings, it was a done deal. In summer 2011, I would be working with Minds Abroad to lead Riverdale students on a three week trip living in Kunming and traveling around Yunnan. I am now counting down the days.
