Anyone take advantage of any of the Design conferences out there, like the Adobe or HOW Design conference? I'm thinking about going to the CS3 workshop in Philly June 3rd, it's free (not including airfare or hotel). I've been to a number of tradeshows with my different jobs and have really developed a number of great networking opportunities, but never actually been to a design conference. Just curious what ya'll have done or what you think about them.
