Most unusual circumstance or location in which you've gamed
Wow, I must be pretty boring, because mostly I've gamed in college dorm common rooms or game stores or people's houses.
Wait, wait! I once ran a quick pick-up game of Star Wars at my brother-in-law's bachelor party because the best man had really dropped the ball on planning something. It was a bit of a thrown-together mess but WEG Star Wars is really good for that kind of thing.
