Three times a year, there's Strategicon convention, and I go for the board games. It happens Presidents Day, Labor Day, and Memorial Day weekends. You go and take a look at the new board games and meet a couple of board game designers, and you can check out games you don't own from the library and then return them.
Improv definitely made me a better auditioner, without a doubt. We did do an audition semester in grad school, and that was helpful for those times that you have a script and you have a few days to prepare it, to really work on sides. But the auditions I was doing in New York, if you got it the night before, you were very lucky.
Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.
