Wow. I can't believe this.
I attended CTY 1996-1999.
1996: Astronomy, JHU 1997: Mathematical Modeling, Lancaster 1998: Paleobiology, Lancaster 1999: Engineering (I forget the actual title of the class), JHU
People I remember...Zoot and Mishkin (I had forgotten Mishkin existed until I read the Digiclan page), I think there was another girl named Zanna...I was the "Emily" in "Four Jennifers and an Emily" in Astronomy 1996, if anyone remembers that...
I attended the Passionfruit in 1998, but I don't remember if they had those at Hopkins the year afterwards.
I still keep vaguely in touch (via livejournal) with Amy R. and Matt K. from '98, but they're it.
I found this wiki by Googling on "Lancaster Canon" (I had wanted to make myself a mix cd for the car), and...well, here I am.
This is a fun article about summer camp on Slate.
