Am definitely back from GenCon. Fun was had, though I didn't manage to catch up with Lisamarie (totally spaced it on Sunday, and one of my seminars was longer than I had thought it was, which cut into what I thought was my free time), but I'm writing up some more details, which I will post soonest.
I highly recommend Indianapolis as a convention city, though. The GenCon staff left a lot to be desired (the lines were huge and tres slowly moving, but I didn't have to deal with any of the, so..), but overall I loved the new venue. Can't wait to go back next year.
