In March and April of 2006, Eastern Michigan University had me up for a full 7 weeks (the longest teaching trip I've ever been on) and I had plenty to keep me busy. A public talk, 2 teachers' workshops, 2 young people's workshops and countless class visits, but the heart of the trip was the our weekly Saturday seminar.

Thanks to everyone at EMU for the warm welcome and many exciting experiences, but thank you, above all, to my students for their hard work and participation -- and some really cool final projects!
