I want to chip in my thanks to everyone who helped organize this, to the two tremendous GMs I had (
Henry and 
NCSUCodeMonkey), and to the other players in my games, who were uniformly great.
 
Some of my favorite moments:
* Discovering how truly and really flexible AU magic is.  When it came time to pull out the big guns for a fight, I found myself casting a heightened web spell, incidentally giving it the electrical template, which, when combined with my electrical mage specialty, gave it yet another ability.  Although it took us a minute or two to sort out all the spell's effects (entangling, damaging, and stunning), it was a lot of fun.
* 
NCSUCodemonkey prefaced his Grimm game with an apology for not having had much time to prepare it.  Inwardly I groaned and thought, "Great, a sloppy seat-of-the-pants game.  This is gonna suck."  Later, when he pulled out the twelve-line poem that he and his fiancee had written together as one part of a multi-part riddle, I thought, "What the heck was he talking about, 'not being prepared'?"  And then still later, when he pulled out a box of Connex (sp?), silly putty, Play-doh, rubber bands, and bendy-straws for us to use in-character to build a contraption for the adventure's climax -- when all us players shouted in unison, "You brought play-doh?  YAYYYYY!!!!!" -- I decided that if this was 
NCSUCodemonkey's idea of unprepared, I desperately want to play in a game that he actually takes the time to prepare for.  I expect he must write odes in the original Sumerian and build life-sized sets

My two favorite quotes from the day:
 
"Unfortunately, you have to be a level six Nerd to do that." -
NCSUCodemonkey in the Grimm game, answering a player's question about what his Nerd character could accomplish.
"Don't think of yourselves as losers!" -- The woman running the raffle, speaking to those losers who didn't win anything.
 
Thanks again, all!
