I went last year, when it was in Chicago... Trotter was the keynote speaker. My district isn't covering the tab for this years' trip. I guess I can't blame them. I read that (ChefTalk's own) Andrew Dornenburg and Karen Page are giving the keynote address and Sarah Moulton is the Gala Dinner guest.
You should have a great time. Last year, I met tons of people for networking and learned much about bringing the kitchen into the classroom. There was a really good manufacturer's exhibit that included book pubishers, uniform suppliers and various commodity industry reps. Have a great time!
