I'll be attending. If you'll be there and would like to meet up, please email me. I'm suevanhattum on hotmail.
I'm planning to buy a few books I've heard good things about:
Euler's Gem, by Dave Richeson, who blogs at Division by Zero,
The Calculus of Friendship, by Steven Strogatz (read Sam Shah's review),
and some of James Tanton's books.
