I'm thinking of wearing a card on my hat that says "Im Garch." Is that a good or bad idea? I'd like to know so I can decide if I should do it or not. Change: After hearing how much most people like the idea, I've decided to change this topic into one about how to notice you at nats. So post how others will notice you there. Mine is, as I said, I'll have a card on my hat that says I'm Garch.
