The NaNoWriMo Seattle region's mascot is the duck. We identify each other in random cafés by rubby duckies on the tables. I brought mine with me to a write-in last night, but in my rush to catch my ride when I left, I forgot to put my ducky back in my bag!
I've sent a message to the guy who organized the write-in, hoping that he has my ducky. In the meantime, I've made myself some rubber ducky Post-It Notes (sticky side is the base of the ducky) so I can still be known to my fellow WriMos. :)
