Taping it onto the balloons! Wow. I can just imagine the opportunities for error that can provide if things are really rushed. =>

Yes, I can see that if the visual path through a path is well-understood by everyone, by convention, balloons might not be put to that use. I need to come back to this after I've had time to look at the pages telophase posted--the extent to which Western conventions might not help people new to the genre, or not visually inclined.
