I was part of Friday's flight in Seattle. Due to a parking snafu, I was late arriving. Fortunately, I get there and am tools they hasn't started yet, so I quickly made my way to my table and start setting up. As I do so, I realize that all of my pilot and upgrade cards for my fleet were still sitting on my kitchen table, where I had double checked them to make sure they were all there.
I tell my opponent and go to the TO, thinking maybe I can shift to Saturday's flight. Instead, he asks the room if anyone has the cards I need. Within minutes, three different people have hooked me up with the cards I forgot so I can get flying.
That, right there, is why the X-Wing community is awesome. Fly casual, folks.
