I also went out to the cafe and drew for a few minutes. It was emptying out by the time I got there, so I really didn't get much done. I ended up taking out my pen and a bottle of ink and making a few nice little sketches. The pen and ink wasn't as noticeable as I thought it would be, but that might be because there was practically nobody in the cafe to notice. Anyway, a brush would be really obvious, so I don't think I'll ever do that.
